b1e079b68b core: move rule to create basic directories
Some of those directories will be needed even during configuration, like
BUILD_DIR, where we'll store the generated kconfig snippet.

So, move the rule to create them outside the BR2_HAVE_DOT_CONFIG block.

9429e7b698 core: introduce an intermediate rule before the configurators
Currently, all configurators depend on generating the out-of-tree
Makefile wrapper.

In an upcoming patch, we'll need to also generate a kconfig fragment,
so it will have to kick in before we run the configurators.

Introduce a new intermediate "prepare-kconfig" rule, so we can
commonalise the dependencies of the configurators. Move the dependency
on the Makefile wrapper to that new intermediate rule.

666edc7aa0 core: commonalise the bundled and br2-external %_defconfig rules
The code for both cases is exactly the same, and only differs in the
location where defconfig files are looked for.

We use an intermediate macro to generate the corresponding rules,
because directly generating the rules is ugly and needs lots of escaping
and double-dollar-ing for the $(eval ...) and $(foreach ...) calls to
play nicely together.

Furthermore, that will be tremendously useful when we support multiple
br2-external trees.

242e0087e5 core: move pkg-utils.mk to support/
pkg-utils.mk contains various definitions that are used in the package
infrastructures and packages themselves.

However, those definitions can be useful in other parts of Buildroot,
and are already used in a few places that are not related to the package
infrastructure. Also, $(sep) will be needed early in the Makefile when
we eventually support multiple br2-external trees.

Since this file only contains definitions, we can include it anytime.

So, consider that file to no longer be specific to the package infras:
  - move it to support and rename it,
  - move a few similar definitions from the main Makefile to that file.

66a5fc74e7 core: name the package before its help text
Currently, all our internal packages provide actions that are prefixed
with their own names. This makes it obvious what package the action
refer to.

However, the help commands are really free-form. This means that
packages (and especially packages from a br2-external tree) may provide
completely arbitrary help text.

As such, all that text can get pretty easily mixed up, and it will be
very difficult to read.

Prefix each package-specific help text with the name of the package it
refers to. This generate a "make help" that looks like:

    [...]
    Package-specific:
      <pkg>                  - Build and install <pkg> and all its dependencies
      <pkg>-source           - Only download the source files for <pkg>
      <pkg>-extract          - Extract <pkg> sources
      <pkg>-patch            - Apply patches to <pkg>
      <pkg>-depends          - Build <pkg>'s dependencies
      <pkg>-configure        - Build <pkg> up to the configure step
      <pkg>-build            - Build <pkg> up to the build step
      <pkg>-graph-depends    - Generate a graph of <pkg>'s dependencies
      <pkg>-dirclean         - Remove <pkg> build directory
      <pkg>-reconfigure      - Restart the build from the configure step
      <pkg>-rebuild          - Restart the build from the build step

    busybox:
      busybox-menuconfig     - Run BusyBox menuconfig
      busybox-nconfig        - Run BusyBox nconfig

    barebox:
      barebox-menuconfig     - Run barebox menuconfig
      barebox-savedefconfig  - Run barebox savedefconfig

    linux:
      linux-menuconfig       - Run Linux kernel menuconfig
      linux-savedefconfig    - Run Linux kernel savedefconfig
      linux-update-defconfig - Save the Linux configuration to the path specified
                               by BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE

    Documentation:
      manual                 - build manual in all formats
      manual-html            - build manual in HTML
      [...]

(Note: busybox, barebox, linux help will be converted in followup
commits, they are represented here as an example of what this patch
does look like.)

Steps to reproduce failure:

- enable BR2_ROOTFS_MERGED_USR
- mkdir some_path/rootfs-overlay/lib/firmware/some_file.txt
- enable BR2_ROOTFS_OVERLAY="some_path/rootfs-overlay"
- run 'make'
- 'target/lib' contains only the files from 'some_path/rootfs-overlay/lib' instead
  of the original symlink 'lib -> usr/lib'.

bbe29b9896 purge-locales: Handle empty locale directories better
If a locale directory is empty, shell code like "for langdir in
$$dir/*;" will loop once with langdir set to "path/to/dir/*", rather
than not looping at all, which would obviously be the desired
behavior.

Then "grep -qx $${langdir##*/}" ungoes two shell expansions (how?)
that transform the expression from "${langdir##*/}" to "*" to "list of
all files in buildroot root dir".  Which is most certainly not what
this command was supposed to do.

If one of those files happens to be an 8GB flash image, grep consumes
all available memory and crashes trying to search it.

This reverts commit 84c825f8e8.

Turns out that the custom help is not available when the $(O) directory
has not been configure yet (i.e. when there is no .config already
filled).

Rather than trying to work around this limitation with dirty hacks, just
revert this feature. After all, this will not prevent an external.mk
from providing custom help anyway; it's just not gonna be advertised nor
displayed with the main help.

376737d99d Makefile: reset LD and AR environment variables
The goal is to fix the compilation of perf (from linux) when LD or AR

After the linux upstream commits 5ef7bbb09f7b ("perf tools: Allow to
specify custom linker command") and 3c71ba3f80bb ("perf tools: Really allow
to specify custom CC, AR or LD") CC, AR, and LD variables are not overridden
if they are inherited.

In case of a cross compilation, it results in an inconsistent state: CC is
overridden but not LD and AR.

84c825f8e8 core: add the possibility to provide help for custom rules
When using a br2-external tree, it is possible (as stated in our manual)
to implement whatever arbitrary extra make rules (such as flashing a
board, or extracting the rootfs in an NFS export...). Some of those
extra rules might be exposed to the user as new entry points that the
user can call by itself.

However, there is no way for the br2-external to advertise those new
rules in the help text.

We add the possibility to do so, by adding a new make rule, called
help-custom, advertised in our own help info.

It is up to the br2-external tree to provide whatever help text is
deemed necessary. The format of the help is completely free-form.

Note that we need to provide an empty, dummy help-custom rule, since it
is always advertised (making it .PHONY does not work). Since this rule
is empty, make gently reports that there is "Nothing to be done for
`help-local'", which is pretty well fitting when help-local was not
provided (either because there's no br2-external tree, or when the
br2-external tree does not provide it.

5e7020ef64 core: catch failures in graph-depends
Currently, we generate the dependency graph in a single command, piping
the stdout of support/scripts/.graph-depends to the stdin of dot.

Unfortunately, this means we can't catch a failure of graph-depends, as
the shell can only treturn the exit code of the last command in a pipe.

Still, we do want to keep the output of graph-depends, and we in fact do
keep it by mean of a tee.

graph-depends has just gained the ability to generate its output to a
file, so we break the pipe in two differnet commands, so we can bail out
on graph-depends errors.

Do that for the two call sites.

91ea933127 core: fix setting of HOSTARCH
Currently, we set HOSTARCH to the output of `uname -m`. This gives us
the architecture as seen by the running kernel. For example, we would
end up with 'x86_64' for a 64-bit kernel running on an x86_64 processor.

We use that value to determine whether we can run some binary tools,
like our pre-configured external toolchains.

However, one may be running a userland in a different bitness than that
of the running kernel. For example, one may run in a 32-bit chroot, even
though the kernel is running in 64-bit.

Up until recently, this was not an issue because the pre-configured
external toolchains were all requiring an i386 (x86 in Buildroot
parlance).

But since we introduced the latest Linaro toolchains, we now have
toolchains that require a 64-bit userland.

So, when running on a 64-bit kernel, we believe those toolchains are
available, even when the user is running a 32-bit userland. This causes
build failures for our autobuilders, like so:

    http://autobuild.buildroot.org/results/9cd/9cdf10ec5b31144b2e03ea09cf128702339895b3/

with the following symptoms:

    >>> toolchain-external undefined Configuring
    Cannot execute cross-compiler '/home/test/autobuild/instance-3/output/host/opt/ext-toolchain/bin/aarch64-linux-gnu-gcc'

So, instead of relying on the output of `uname -r`, look for the host
gcc and extract the target it was configured to generate code for.

Fixes:
    http://autobuild.buildroot.org/results/9cd/9cdf10ec5b31144b2e03ea09cf128702339895b3/  (aarch64)
    http://autobuild.buildroot.org/results/888/8889aa7d9fb48370e4760a6edbc6d3ae945f02f2/  (arm)
    and many more...

Besides fixing those issues, it will also allow us to add the 64-bit
variants of toolchains when they exist, like the upcoming Codescape
MTI and IMG toolchains for MIPS from Imagination Technologies.

3e1b33a534 pkg-generic: improve incorrectly used package detection
Currently, the check that packages we build are indeed enabled is done
at the time a package is configured.

This can come quite late in the build process, and does not provide
direct knowledge of the real culprit for the incorrect dependency.

However, we can improve these two issues quite easily, albeit at the
expense of a very slightly more complicated make code.

First, the check can not be done at the time we define the package, i.e.
in the inner-generic-pacakge, because all its dependencies might have
not been parsed yet, so we can't yet know whether it is enabled or not
(because we can't match the package name of the dependency to its
Kconfig variable yet).

But then, we know we have all packages definitions after we scanned the
the bundled packages, kernel, bootloaders and toolchains, as well as the
br2-external tree (if any).

So, at this location, we iterate through the list of enabled packages,
and check that the packages they each depend on are indeed enabled.

This allows us to:
 1- do the check very early, before any build action,
 2- report on the exact offending package very easily.

9c40723489 Makefile: drop ldconfig handling
The ldconfig handling in the main Makefile is utterly broken, as it
calls the build machine ldconfig to generate the ld.so.cache of the
target. Unfortunately, the format of the ld.so.cache is architecture
specific, and therefore the build machine ldconfig cannot be used
as-is.

This patch therefore simply drops using ldconfig entirely, and removes
/etc/ld.so.conf.d/ from the target skeleton. The idea is that all
libraries that should be loaded by the dynamic linker must be
installed in paths where the dynamic linker searches them by default
(typically /lib or /usr/lib).

This might potentially break a few packages, but the only way to know
is to actually stop handling ldconfig.

In order to be notified of such cases, we add a check in
target-finalize to verify that there is no /etc/ld.so.conf file as
well as no /etc/ld.so.conf.d directory.

376fda8f99 core/printvars: allow dumping a set of variables
Dumping our 176164 variables can take quite some time (~12s here). What
takes the most time is sorting the variables (~9s), followed by the
parsing of our Makefiles (~3s), with the actual printing in the noise.

However, sometimes only one or a few variables are needed. For example,
one may want to retrieve the Linux build dir from a post-build hook (to
get the Linux' actual .config after our fixups and check for various
features).

Add the possibility to only dump the variables listed in $(VAR) which
must be passed as a make argument, like so:

    $ make -s printvars VARS="LINUX_DIR TOPDIR O"
    LINUX_DIR=/home/ymorin/dev/buildroot/O/build/linux-4.3 ($(BUILD_DIR)/$(LINUX_BASE_NAME))
    O=/home/ymorin/dev/buildroot/O/. (/home/ymorin/dev/buildroot/O/.)
    TOPDIR=/home/ymorin/dev/buildroot/buildroot (/home/ymorin/dev/buildroot/buildroot)

It is also possible to use make-appterns, like:

    $ make -s printvars VARS="BUSYBOX_%"

This is much faster (the time is just about the time it takes to parse
our Makefiles, 3s here) and easier to parse.

[Thomas: improve comment above the printvars target.]

cb34ea5d6a package/skeleton: also handle merged /usr in the staging
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.

0ea851c0c0 core: do not accept multiple definitions of a package
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.

b9f4727ff4 legal-info: allow to declare the actual sources for binary packages
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.

[Thomas:

    never be triggered due to how the conditions were

2e32330c4a Makefile: unexport O
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.

1e9f604716 Makefile: fix performance regression caused by the umask handling
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.

This directory is populated as $(BUILD_DIR) (==$(O)/build), while O is
set explicitly from the release target to a subdirectory
buildroot-xxxx.yy-git/ which was populated with 'git archive'.

Since the generated manuals are available in docs/manual, which is
also referred to from the README, the build directory is not needed and

The infrastructure are modified to filter host-skeleton.
It's needed becauses the host-dependencies are derived from the

The /usr/share/X11/locale/locale.dir file is needed by libX11.
Removing it breaks locale support in X11. However, make removes
not only directories but also all files, which are not listed
in the BR2_ENABLE_LOCALE_WHITELIST.

This re-creates locale.dir database file where needed.

361d3573f5 Makefile: don't depend on current skeleton/overlay permissions
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.

bee5745ccc Makefile: don't depend on the umask
Some packages and BR itself create files and directories on the target
with cp/mkdir/etc which depend on the umask at the time of building.

To fix this, use a trick inside the Makefile which wraps all rules when
the umask is not 0022. This sets the umask at the top level, and then
the building process continues as usual.

[Thomas: add --no-print-directory, as suggested by Arnout.]

1668e1da39 packages: fix and improve support for top-level parallel make
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

307029867b Makefile: Don't export VERBOSE unless V=1 (for CMake)
CMake verbose mode is based on VERBOSE environment variable.
* If VERBOSE is exported but empty, only "Dependee ... is newer than
depender ..." messages are shown.
* If VERBOSE is exported and set (whatever the value), all compilation
commands are shown.

VERBOSE is currently systematically exported by Buildroot, even if it
is empty, in the root Makefile, which implies that the "light" verbose
mode - with "Dependee ... is newer than depender ..." messages - is
always enabled.

VERBOSE should only be exported when V=1, which is the standard way to
enable verbose mode in Buildroot.

make savedefconfig BR2_DEFCONFIG=my_custom_defconfig

BR2_DEFCONFIG is set in my_custom_defconfig with an absolute path
to qemu_arm_versatile (value present in .config) and set in
my_custom_defconfig as it is different from default mentioned in
config.in (default is BR2_DEFCONFIG from environment).

On savedefconfig recipe, simply remove BR2_DEFCONFIG from generated file

e4dde2536a Makefile: Handle whitespace when stripping .ko
It is possible to end up with a path containing spaces if the kernel
localversion contains spaces.
Be it good practice or not, there are third party vendors which
distribute kernel configuration files for reference platforms which have
quoted strings containing whitespaces in the localversion.

There was already a fix to handle paths with whitespaces or other
special characters when running strip, which consists of using the find
-print0 and xargs -0 pair of arguments, but the kernel module stripping
wasn't included in the fix.
This commit includes the same fix to the kernel module stripping line.

4feeb2db34 Makefile: add a few more targets to nobuild_targets
With this commit, one can now execute the source-check, external-deps
and legal-info targets regardless of the checks normally being done by
packages on the configuration.

Note that we intentionally do not go down the road of adding %-source,
%-legal-info, and the miryad of other targets that could work in such
situations. We only whitelist a few targets that are really useful to
have as nobuild_targets.

[Thomas: also add 'clean' and 'distclean' to the nobuild_targets, as
suggested by Yann.]

256f142bf6 Makefile: add BR_BUILDING variable
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.

7800b9619d Makefile: move source-check outside of noconfig_targets
make source-check is here to check whether the remote sources for the
current selection of packages are still available. In its current
implementation, since it simply calls recursively a sub-make with the
source target, it can be a noconfig_targets. However, a follow-up
change will make source-check not use a sub-make, which will require
it to no longer be a noconfig_targets.

Therefore, as a preparation, this commit moves source-check outside of
noconfig_targets.
