When the target uses a merged /usr setup, gdbserver will only report
paths in /lib to the remote gdb, which in turn will only look for
libraries in staging/lib and never in staging/usr/lib.
So. the merged (or non-merged) /usr setup must be replicated in the
staging.
The best solution where to do so is in the skeleton package, since it
is guaranteed to come before any package that installs things in the
staging, and even before the (internal or external) toolchain as well.

One of the selling points for br2-external is to provide a mean to add
new packages. However, it is not supported that a package be defined by
Buildroot and then redefined in a br2-external tree.
This situation may occur without the user noticing or even willing to
redefine the package, for example:
- br2-external is first created against a version of Buildroot
- a package (missing in Buildroot) is added to that br2-external tree
- upstream Buildroot adds this package
- user updates to the new Buildroot
In this case, the result in undefined, and we can't make any guarantee
on the result (working or not).
Add a sanity check so that a package redefinition gets caught.

The FOO_SITE/FOO_SOURCE variables usually point to a tarball containing
source code.
For the downloaded external toolchains this is not true, the "source"
tarball actually contains binaries. This is fine for making Buildroot
work, but for legal-info we really want to ship real source code, not
binaries.
Luckily, some (hopefully all) toolchain vendors publish a downloadable
tarball containing the source code counterpart for their binary
packages.
Here we allow the user to declare the URL of this other tarball in the
pair of variables FOO_ACTUAL_SOURCE_TARBALL (by default equal to
FOO_SOURCE) and FOO_ACTUAL_SOURCE_SITE (by default equal to FOO_SITE).
If the "actual source" package can be downloaded from the same
directory as the binary package, then only FOO_ACTUAL_SOURCE_TARBALL
needs to be set.
Note this change is not strictly toolchain-specific: it might be useful
for other packages that happen to ship binaries in the same way.

After bee5745ccc ("Makefile: don't depend on the umask"), any use
of "make O=<dir>" would leak $O into the enviroment for submakes,
and it's inherited by package makefiles. Some package makefiles have
protections to make sure they don't use the value of $O if it comes from
the enviroment (Linux), but some don't (uClibc).
This caused build failures when using a different output dir.
Fix this by unconditionally unexporting the O variable, since we never
need to have it set in the environment for packages, it should be only
internally used by BR.

Commit bee5745c introduced an extra level of 'make' when the umask is
different from 0022. However, when several targets were specified on
the command line, a new make instance would be called for each target.
This introduces a huge performance overhead when many targets are
specified on the command line.
To fix this, use the same approach as used in the mkmakefile script:
an addition target on which the MAKECMDGOALS depend, so that this
target is run only once.
Note that the mkmakefile script contains a special exception for
Makefile, because the Makefile in the output directory is generated.
Since the top-level Makefile is not generated, this exception is not
needed here.
While we're at it, also fix the whitespace in the UMASK assignment.

We use 'rsync -a' to copy the skeleton and overlays, so the target ends
up with the exact same permissions as on the repo. The problem is we
don't track these permissions, since Git doesn't allow for that (except
for the exec bit). This means users with different umasks at the time of
cloning could end up with different target permissions.
Fix this by using --chmod on rsync calls so we don't depend on the
current permission set for the skeleton and overlays. We do depend on
the exec bit, but that's fine since that one is tracked by Git.

The boost and jack2 packages fail to build when PARALLEL_JOBS is empty
so instead of using an empty PARALLEL_JOBS don't use it in the MAKE
variable when top-level parallel make is being used.
To simplify the use of top-level parallel make, check the MAKEFLAGS
variable to know automatically if the -j option is being used, also use
the "=" operator instead of the ":=" operator because the MAKEFLAGS
variable can be checked only in a "recursively expanded variable".
The "override" keyword must be used in order to change the automatic
variable "MAKE".
When the top-parallel make is being used the sub-make are called without
specifying the "-j" option in order to let GNU make share the job slots
specified in the top make. This is done because GNU make is able
to share the job slots available between each instance of make so if you
want to increase the number of jobs you just need to increase the <jobs>
value in the top make -j<jobs> command.
If we specify the -j<jobs> option in each instance of make, it is less
efficient, e.g. in a processor with 8 cores we specify -j9 in each instance:
the number of processes goes up to 81 because each sub-make can execute
9 processes. The excessive number of processes is not a good thing
because in my tests even -j16 is slower than -j9.
Instead if we don't specify the -j<jobs> option in the sub-make, the top
make share the job slots automatically between each instance, so the
number of process in this examples goes up to 9 that is faster than
using up to 81 processes.
e.g. when the -j3 option is specified only in the top make:
possible state n. 1:
process 1 - <packagea>-build
process 2 - <packagea>-build
process 3 - <packagea>-build
possible state n. 2:
process 1 - <packagea>-extract
process 2 - <packageb>-configure
process 3 - <packagec>-build
possible state n. 3:
process 1 - <packagea>-build make -j1
process 2 - <packageb>-build make -j1
process 3 - <packagec>-build make -j1

Some packages do some sanity checks on their configuration, for
example linux checks that the defconfig string is not empty when a
defconfig is used. Such checks are currently always performed, except
when the 'source' target is part of make goals.
This is problematic for two reasons:
- Other targets such as 'source-check', 'external-deps' or
'legal-info', that do not consist in doing a build, cannot be
executed in such situations.
- The current code removes the check as soon as one of the targets is
source. But if there are other non-source targets called at the
same time, the checks are ignored.
This commit therefore introduces an internal variable called
BR_BUILDING, which tells packages if we are actually building or
not. A variable nobuild_targets indicates the targets that we do not
consider as being build targets.
For the moment, nobuild_targets only contains 'source', to be
completely iso-functional.

$(HOST_DEPS) variables that we are trying to remove.
It is worth mentionning that this commit might change the output of
'make legal-info' by making it more correct than it was. With the
existing implementations, we could be missing packages if they were
host packages, or target packages not properly selected in terms of
Config.in dependencies, and with a more than a two-level deep
dependency from a target package properly selected at the Config.in
level. This is because our previous logic was simply taking all
packages in the "TARGETS" (now called "PACKAGES") variable, which are
only the target packages explicitly selected in the .config file, and
doing a two-level deep recursion in the dependencies.
With this commit, we switch legal-info to use proper make-based
dependencies, so we no longer have the limitations we used to
have. For this reason, the output of 'make legal-info' after this
patch may contain *more* entries than before this patch, but it is

The main Makefile was declaring a subset of the per-package targets as
being PHONY, but not all of them. Now that the pkg-generic package
infrastructure is taking care of that in a much more systematic
fashion, this commit gets rid of the unneeded code from the main
Makefile.

In 8a46d4bf1f the randpackageconfig and allpackageyesconfig were
extended with disabling all the legacy options, otherwise the resulting
config couldn't be built. However, that didn't work for randconfig and
allyesconfig.
This commit reverts 8a46d4bf1f and replaces it with a different
approach: skipping of the legacy config options is passed explicitly
through the environment variable SKIP_LEGACY, which forces
BR2_SKIP_LEGACY to y. The new option BR2_SKIP_LEGACY completely
disables the legacy handling, which effectively removes all the legacy
options from the .config.
However, in that case no values are set for the legacy options so a
subsequent oldconfig will query them. Therefore, run an additional
olddefconfig.

This definition of HOSTFC is completely wrong.
"$(HOSTLD)" should be "$(HOSTFC)". Also, "echo" always succeeds, so
"which g77 || type -p g77 || echo gfortran" is never run.
Anyway, HOSTFC is most likely set to "/use/bin/ld" and nobody has
complained about it before me, so I guess it is not used at all.

>From `info make` documentation, origin will return
`undefined'
if VARIABLE was never defined.
`command line'

Therefore, $(origin V) will get a value anyway, killing ifdef/endif

Furthermore, I've checked the minimal requirements from the top
Makefile is GNU make 3.81, and that version of GNU make has support
of origin function well already, so now it's safe to kill the outer

The global .PHONY specification in the main Makefile is describing a
number of directory targets as being PHONY, which doesn't make much
sense. PHONY targets are targets that do not exist on the filesystem,
and which make should always consider as not being up-to-date, so that
the commands associated to these targets are always executed by make
when the command is invoked, even if a file with the same name exists

Special characters in files or directories in the rootfs can cause
problems when stripping files. For example "target/some song.mp3"
gets treated as two entries. "target/some" and "song.mp3" are both
passed to $(STRIPCMD). This then errors saying files don't exist.
Additionally a ' and possibly other special characters in a file path
causes xargs to give the error: "xargs: unmatched single quote; by
default quotes are special to xargs unless you use the -0
option". This also has the effect of removing this entry and further
entries from the list of files to strip. This can be demonstrated by
having a test directory with the files: "cat" "rabbit's"
"elephant". then running the command: "find -name "*" -print | xargs"
To fix this we pass -print0 to find which seperates entries with a
NULL character, and we pass -0 to xargs to tell it to only use NULL
characters as the deliminator.

Buildroot unexports PKG_CONFIG_PATH in the top-level Makefile for purity
reasons. But it has an unfortunate side-effect in that "make menuconfig"
will not (necessarily) be able to pick up ncurses via host pkg-config,
breaking "make menuconfig" on systems where ncurses is installed in a
non-standard location.
This patch saves the original PKG_CONFIG_PATH variable in
HOST_PKG_CONFIG_PATH and restores the original PKG_CONFIG_PATH variable
only in the sub-processes that builds the various menuconfig/nconfig/...
targets.
(PKG_CONFIG_PATH has to be placed in front of the make command so that it
propagates to sub-processes. If given as an argument, it doesn't work.)

The GENERATE_LOCALE variable is used for the qstripped version of
BR2_GENERATE_LOCALE. It was used by both the glibc locale generation
code (in the main Makefile), and by the uClibc logic in
package/uclibc/uclibc.mk. However, since commit
33de740170 ("Makefile: convert
"target-generatelocales" to a hook"), this code has been moved around
in the main Makefile, and the definition of GENERATE_LOCALE is now
*after* uclibc.mk is included, and therefore this variable is always
empty when uclibc.mk looks at it for its conditionals. Moreover, it is
now only defined in the main Makefile is BR2_TOOLCHAIN_USES_GLIBC is
'y', which obviously isn't the case for uClibc toolchains.
Since it's anyway not very clear to have this variable shared between
the glibc locale generation logic in the main Makefile and the uClibc
configuration code in uclibc.mk, this commit:
- Renames the GENERATE_LOCALE variable in the main Makefile to
GLIBC_GENERATE_LOCALES.
- Renames the GENERATE_LOCALES hook to GENERATE_GLIBC_LOCALES, since
it's specific to glibc.
The fix for the uClibc case is part of a followup commit.

Currently, the only way br2-external may generate a document is by

But external.mk is only parsed when the tree is configured.
This is unlike our internal document (the manual) which can be generated

So, include the documents from br2-external at the same time we include
our own document:
- expect the same layout as we have: docs/DOC_NAME/doc-name.mk
- do not fail if there is no document: use "-include", not "include"

Currently, pkg-utils.mk (included via package/Makefile.in) is only included
when a configuration file already exists. This means that none of the
utilities it defines are available without .config.
In particular:
- the MESSAGE macro, causing pretty build output. Since some make targets
can be run even without .config, like 'make manual', not having this
pretty printing is odd.
- pkgname, pkgdir: in a subsequent patch, these functions will be used for
the generation of the manual, and since this should work also without
.config, we need these functions to be available.
This patch moves the include of pkg-utils.mk from package/Makefile.in to
Makefile, outside of the check for .config.
This is a quick fix. The full solution involves to minimize the amount of
Makefile code that is guarded by a check on .config. This approach will be
taken in the 2014.11 release cycle.

The gconv libraries are used to translate between different character sets
('charsets', even 'csets' sometimes). Some packages need them to present
text to the user (eg. XBMC Gotham).
In (e)glibc they are implemented by the internal implemenation of iconv,
called gconv, and are provided as dlopen-able libraries.
Note that some gconv modules need extra libraries (shared by more than
one gconv module), so we must, when adding a subset of modules, scan the
installed modules in search of the missing libraries.

Currently, we use such an environment variable to pass the maximum depth

contains just the depth.
However, there has been so far no release of Buildroot which would make
use of that variable, so no user should have come to rely on it.

If a kernel module is installed with incorrect permissions (0755 iso 0644),
it would get stripped in a way that would render the kernel module broken.

Some users would like to get the dot program to be able to further
customise the generated graphs (eg. modify the layout, colorise some

So, store the intermediate dot program alongside the generated graph.

This variable contains extra environment variables that we can not export
since they are clashing with some build systems (eg. BUILD_DIR with

So, we may need these variables for uses other than the user's hooks

The parallel build patch series has significantly reworked how some of
the core dependencies are expressed. We now have the following
dependencies:
all: world
world: target-post-image
target-post-image: $(TARGETS_ROOTFS)
with TARGETS_ROOTFS containing the list of root filesystem image
targets, each having the following dependencies:
$$(BINARIES_DIR)/rootfs.$(1): target-finalize $$(ROOTFS_$(2)_DEPENDENCIES)
The bottom line is that the "target-finalize" target, which in turns
ensures that all packages are built, is only triggered if at least one
filesystem image is enabled.
As we want to support builds with no filesystem image selected, this
is not acceptable. As a fix, we change the target-post-image target
to:
target-post-image: $(TARGETS_ROOTFS) target-finalize
This way, target-finalize will be triggered even if TARGETS_ROOTFS is
empty. This is still correct for parallel build, as the individual
root filesystem image targets still depend on target-finalize.

Our current stripping strategy requires that shared libraries have the
executable permission. However, this is by far not something
recognized as a standard behavior: Debian/Ubuntu distributions for
example do not have executable permissions on their
libraries. Therefore, pushing to upstream packages fixes that add the
executable permissions is not easy.
As a result, this commit improves the stripping logic so that it not
only strips the files that are executable, but also the ones that
match '*.so*', which should match both the shared libraries and the
dlopen()'able plugins, as long as they have a .so extension.
Thanks to this addition, a number of manual "chmod +x" done by various
packages can be removed.

If two files with the same relative paths exist in multiple overlay
skeletons, and they have the same modification time and size, then rsync
might not copy the later file on top of the earlier file. This patch fixes
this by adding the -I option to the rsync commands used in the overlay
skeleton file installations. ("man rsync" indicates that this option turns
off the file-size/mod-date "quick check" behavior, causing all files to be
updated - more like the cp commands that we had originally.)

Since we use the same variable, if the user's environment already

This commit allows the BR2_EXTERNAL directory to contain Config.in and
Makefile code, which gets integrated into the Buildroot build logic:
- Buildroot automatically includes the $BR2_EXTERNAL/Config.in in the
top-level configuration menu.
- Buildroot automatically includes the BR2_EXTERNAL/external.mk in
the build logic, so it can for example be used to include other .mk
files that define package recipes.
This is typically intended to be used to create target packages in the
BR2_EXTERNAL directory, but can also be used for bootloaders, host
packages, or other custom make logic.
We also add a dummy Config.in file in support/dummy-external/ to
ensure that the source "$BR2_EXTERNAL/Config.in" line will point to an
existing file even when BR2_EXTERNAL is not used by the user.

This commit introduces the BR2_EXTERNAL environment variable, which
will allow to keep Buildroot customization (board-specific
configuration files or root filesystem overlays, package Config.in and
makefiles, as well as defconfigs) outside of the Buildroot tree.
This commit only introduces the variable itself, and ensures that it
is available within Config.in options. This allows us to use
$BR2_EXTERNAL in a 'source' statement in Config.in.
Following patches extend the usage of BR2_EXTERNAL to other areas
(packages and defconfigs).
In details, this commit:
* Introduces the BR2_EXTERNAL Kconfig option. This option has no
prompt, and is therefore not visible to the user and also not
stored in the .config file. It is automatically set to the value of
the BR2_EXTERNAL environment variable. The only purpose of this
BR2_EXTERNAL Kconfig option is to allow $BR2_EXTERNAL to be
properly expanded when used inside Kconfig source statements.
* Calculates the BR2_EXTERNAL value to use. If passed on the command
line, then this value is taken in priority, and saved to a
.br-external hidden file in the output directory. If not passed on
the command line, then we read the .br-external file from the
output directory. This allows the user to not pass the BR2_EXTERNAL
value at each make invocation. If no BR2_EXTERNAL value is passed,
we define it to support/dummy-external, so that the kconfig code
finds an existing $(BR2_EXTERNAL)/package/Config.in file to
include.
* Passes the BR2_EXTERNAL into the *config environment, so that its
value is found when parsing/evaluating Config.in files and .config
values.

Buildroot has three places where rsync is used:
1. to copy the target skeleton
2. to copy the rootfs overlay(s)
3. to copy overridden package sources
In all of these cases, we want to exclude version control files by default.
Place 1 and 2 used an identical set of explicit --exclude options, while
place 3 used the option --cvs-exclude. This last option, however, not only
excludes version control files, but also binary files (.o, .so) and any file
or directory named 'core' (a problem for the linux kernel that has several
directories with this name). Moreover, the exact list of excluded files when
using --cvs-exclude depends on the version of rsync.
This patch creates one global variable RSYNC_VCS_EXCLUSIONS that can be used
by the various rsync commands. It excludes the version control files of
svn, git, hg, cvs and bzr.

When calling 'tr' without quoting braces, bash can make really weird things
if there are existing 'single-letter-named' directories

aaa
thierry@thierry-desktop:~$ mkdir m
thierry@thierry-desktop:~$ echo AAA | tr [A-Z] [a-z]
AAA
The (quick) analysis is that the callee (tr) argvs then
contain 'm' thus the translation does not work
Using quotes works around it:

This commit introduces a virtual package called 'toolchain', located
in 'toolchain/toolchain', which simply depends on
'toolchain-buildroot' or 'toolchain-external' depending on the
selected toolchain backend.
For now, toolchain-buildroot and toolchain-external are still manual
make targets, but the following patches convert those backends to use
the package infrastructure as well.
In addition to this:
* The main Makefile is modified to always make BASE_TARGETS point to
this new toolchain virtual package.
* The main Makefile is changed to include all the toolchain/*/*.mk
files: the toolchain virtual package, and the toolchain-buildroot
and toolchain-external directories.
* The dependency of the toolchain on prepare dirs and dependencies is
moved to the toolchain virtual package. It is moved as a
prerequisite of the "toolchain-source" rule to ensure that all
directories are prepared before we even start extracting the
toolchain.

The 'make clean' recipe is using variables that are not defined without
.config file, causing only a partial cleanup when the .config file is
accidentally deleted.
This patch moves those variables that do not depend on values from .config
outside the BR2_HAVE_DOT_CONFIG check, so that 'make clean' is much more
similar with and without .config.
Since HOST_DIR is determined from BR2_HOST_DIR in .config, the host
directory cannot be cleaned correctly without making assumptions, if no
.config is present. However, to cover most people's use cases, we assume
the default value of $(BASE_DIR)/host in this specific case.

The $(BUILD_DIR)/.root rule is executed as part of the 'dirs'
target. The 'dirs' target is re-executed at every execution of 'make
external-deps', and make external-deps explicitly tells make to ignore
targets that have already been made (through the -B option). This
means that the $(BUILD_DIR)/.root rule has to be idempotant, which was
not the case this the introduction of the lib32/lib64 symbolic link.
Running 'make external-deps' three times in a row was sufficient to
trigger an error due to symbolic links being incorrectly created. This
patch fixes that.

libpthread.so has a special stripping condition to preserve parts of
it that are needed for debugging. However, due to the usage of 'xargs'
instead of 'xargs -r', the strip command is executed regardless of
whether a libpthread.so file is found or not. This leads to a big
error message being displayed in static-only builds, because strip is
executed without a file argument. Thanks to the '|| true', the build
continues, but still shows a big error message in the middle, which is
not nice.
By using 'xargs -r', we avoid the strip command from being executed
when 'find' doesn't find any match. We also remove the '|| true' to
catch other real errors.

Currently, when we need to do a conditional on the type of C library
used, we need to take into account the three toolchain backends. As we
are going to add eglibc support to the Buildroot toolchain backend, it
would become even uglier, so this patch introduces two new hidden
options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that
exist regardless of the toolchain backend. The entire Buildroot code
base is converted to use those options.
Note that we have intentionally created only one option
(BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are
essentially the same, as far as Buildroot is concerned.

Store BR2_DEFCONFIG in .config, and use it to update the original input
defconfig file after updating the configuration. When a config is
created by using the BR2_DEFCONFIG=... option, this is saved in the
.config file; later runs of savedefconfig will update that same location.
It is also possible to configure this place in the interactive
configuration.
The BR2_DEFCONFIG value itself is not saved into the generated
defconfig, since Kconfig considers it at its default. This is
intentional, to avoid hard-coding an absolute path in the defconfig.
It will anyway be set again when the defconfig is used with the
'make BR2_DEFCONFIG=... defconfig' command.
As a side-effect of this change, the *config options have been moved out
of the BR2_HAVE_DOT_CONFIG condition. This doesn't make any functional
difference, because the .config is still not read for the *config targets.
However, the defconfig and savedefconfig targets do need to include
.config now, which makes them slightly slower.

The Eclipse plugin at
https://github.com/mbats/eclipse-buildroot-toolchain-plugin allows
users of Eclipse to easily use the toolchain available in
Buildroot. To do so, this plugin reads
~/.buildroot-eclipse.toolchains, which contains the list of Buildroot
toolchains available on the system, and then offer those toolchains to
compile Eclipse projects.
In order to interface with this plugin, this commit adds an option
that allows the user to tell whether (s)he wants the Buildroot project
toolchain to be visible under this Eclipse plugin. It simply adds a
line in this ~/.buildroot-eclipse.toolchains file.

Support scripts (in support/) may need to parse the .config file, so give
them an easy access to it, by exporting BUILDROOT_CONFIG with the fully-
qualified path to .config.
Also, post-build scripts may need to reference a few locations, so export
those, too.
Note: we export both O and BASE_DIR. Although they are the same, BASE_DIR
is used internally, while O is used on the command line, which makes it a
bit ambiguous to know which to use. As users use O= on the command line,
they will probably tend to use that in their post-build scripts.
Update doc accordingly.

changes in buildroot. I.e., we want to make it less likely that a user's

A first step is to make sure that the user is warned about API changes.

A very common mistake done by our users is that they use
output/target/ directory as their root filesystem. Even though this is
loudly documented in our Buildroot manual, people don't read
documentation, so it is not sufficient.
This patch adds a text file named
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why
output/target isn't appropriate to use as the root filesystem. The
process is:
* At the beginning of the build, right after the skeleton has been
copied, support/misc/target-dir-warning.txt is copied to
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM
* In the filesystem images creation code, this file is removed before
launching fakeroot, and restored right after that, so that this
file is not present in the generated root filesystem images.
Note that the file has not been added to the default skeleton for two
reasons:
* It would have annoying to have in our source tree a file named in
capital letters inside system/skeleton/
* The proposed way works even if the user uses a custom skeleton.

This directory groups the following elements:
* the default root filesystem skeleton
* the default device tables
* the Config.in options for system configuration (UART port for
getty, system hostname, etc.)
* the make rules to apply the system configuration options
Even though the skeleton and device tables could have lived in fs/, it
would have been strange to have the UART, system hostname and other
related options into fs/. A new system/ directory makes more sense.
As a consequence, this patch also removes target/Makefile.in, which
has become useless in the process.

This allows to automatically collect material that may be needed to comply with
the license of packages that Buildroot prepares for the target device.
The core of the implementation is made by the following parts:
- in package/pkg-utils.mk some helper functions are defined for common actions
such as generating a warning, producing info about a package etc;
- in package/pkg-gentargets.mk, within the GENTARGETS framework, a new
<PKG>-legal-info target produces all the info for a given package;
- Makefile implements the top-level targets:
- legal-info-prepare creates the output directory and produces legal info
about Buildroot itself and the toolchain, which mostly means just warning
the user that this is not implemented;
- legal-info, the only target that is supposed to be used directly, depends
on all of the above and finishes things by producing the README files from
the various pieces.

The original 'source-check' target first selects all packages, and then checks
whether the package tarballs can be found. This is useful for Buildroot
maintainers, but less useful for developers working on a specific project. The
latter only care about the packages used in that project.
This patch removes the allyesconfig dependency to source-check so that only
selected packages are checked. The original behavior is moved to a new target
'source-check-all'.

The existing ccache infrastructure sets the cache directory hardcoded in the
ccache binary. As this directory was set to ~/.buildroot-ccache, the cache
is not necessarily local (e.g. in corporate environments the home directories
may be mounted over NFS.)
Previous versions of buildroot did allow to set the cache directory, but this
was also hardcoded (so you had to rebuild ccache to change it), plus that
support was removed.
See http://lists.busybox.net/pipermail/buildroot/2011-July/044511.html for
a discussion on this.
This patch modifies ccache to respect a new shell variable (exported from
the Makefile, based on a configuration option) instead of CCACHE_DIR.
The name CCACHE_DIR itself is already used by autotargets for the ccache
package.

In order to use locale support on a Linux system, you need locale data
to be present:
* on a (e)glibc based system, this data is typically in the
/usr/lib/locale/locale-archive file, which can be created and
extended using the localedef program
* on an uClibc based system, the set of supported locales is defined
at build time by an uClibc configuration option.
This patch implements generating locale data for the following cases:
* Internal toolchain
* External toolchain based on (e)glibc. uClibc external toolchains
are not supported, because with uClibc, the set of supported
locales is defined at build time. CodeSourcery and Linaro
toolchains have been tested, Crosstool-NG toolchains are believed
to work properly as well.
* Toolchains built using the Crosstool-NG backend, but only (e)glibc
toolchains.
This feature was runtime tested with internal uClibc toolchain,
CodeSourcery ARM toolchain and Linaro ARM toolchain, thanks to a
simple C program that shows the data and a gettext translated message.
Note that this option differs from the "purge locales" option, which
is responsible for removing translation files and other locale stuff
installed by packages. At some point in the future, we may want to
clarify the respective roles of those options.

There used to be a mechanism using which packages could leave a

The latest user was nfs-utils, which used this mechanism to do the

since 16e7b8255c, nfs-utils has been

Once a profile has been choosen, the user is offered the choice of

the system.
We of course provide a "custom profile", through which the user can
configure Buildroot to use a custom external toolchain for which no
profile is available.

* ccache is now a normal package (both for the host and the target).
* ccache option is now part of the "Build options" menu. It will
automatically build ccache for the host before building anything,
and will use it to cache builds for both host compilations and
target compilations.
* bump ccache to 3.1.3

When sstrip is selected it tries to strip kernel modules too.
Unfortunately this fails with a "unrecognized program segment header
size" error thus interrupting the build process.
We introduce a new $(KSTRIPCMD) strip command for this, being a regular
strip when sstrip is selected and an empty stub when not stripping.
At the same time get rid of the REMOVE_SECTION_* variables, as they are
only used once.

Certain toolchain configs (E.G. on blackfin), don't use symlinks, so the
file name to match is the actual SONAME (.so.*). Support these toolchains
as well.

For proper threading debug support, the libthread_db.so library cannot
be stripped on the target. This is because the target gdbserver will
also load up this library at runtime and poke around its symbols.

Often times, the only reason /usr/share exists is because of documentation
installed into it. So once we're done cleaning the docs, attempt to rmdir
/usr/share. If it's empty, things will work out nicely.

The installed kernel modules should have useless build cruft stripped out
of them. On my system, a default build went from a very unreasonable 30MB
to a normal 3MB (on disk) and from 14MB to 3MB when compressed due to the
info stored in the kernel modules alone.

Ensure host packages (dependencies of target packages) are also handled
by make source / make external-deps.
This has to be done a explicitly, as we don't list these in Kconfig,
and hence also not in a variable like TARGETS, so instead we have to
look at the <PKG>_DEPENDENCIES variables for each enabled package and
extract the host packages from there.
Host packages can in turn also have dependencies, so we have to follow
those as well. Ideally this should be done recursively, but as that's
pretty hard to do in make, it is limited to 1 level for now.
Finally, host packages share source files with target packages, so
pipe output of make external-deps through sort -u to ensure duplicates
are removed.

The configuration cache shared between packages, while being in
principle a nice idea to speed-up the configuration of packages by
avoiding repetitive identical checks, turned out to be unreliable due
to the subtle differences between similar but not identical checks in
different packages. After spending some time trying to fix those, we
concluded that supporting the shared configuration cache is definitely
too hard and too unreliable, and that we'd better get rid of it
altogether.
This patch therefore removes the shared configuration cache
infrastructure and usage.

Some packages use the buildroot version string (to set their own version
string). Computing the version string globally will makes it easy for
them to use it instead of re-computing it in every packages.
