When building in a different output directory than the original build,
there will currently be a lot of ccache misses because in many cases
there is some -I/... absolute path in the compilation. Ccache has an
option CCACHE_BASEDIR to substitute absolute paths with relative paths,
so they wil be the same in the hash (and in the output).
Since there are some disadvantages to this path rewriting, it is made
optional as BR2_CCACHE_USE_BASEDIR. It defaults to y because the
usefulness of ccache is severely reduced without this option.
In addition to CCACHE_BASEDIR, we also substitute away the occurences
of $(HOST_DIR) in the calculation of the compiler hash. This is done
regardless of the setting of BR2_CCACHE_USE_BASEDIR because it's
quite harmless.

Now that we have more options in terms of static/shared libraries,
switch from the existing default of building both shared and static
libraries to building shared libraries only (of course only on
platforms that support shared libraries).
Building both shared and static takes time (since the shared objects
must be built with -fPIC, while static objects are generally built
without, as -fPIC has some performance impact) and consumes a little
bit more disk space.
For example, a static+shared build of libglib2 takes 1 minutes and 59
seconds, with a final build directory of 96 MB. A shared-only build of
libglib2 takes only 1 minutes and 31 seconds (almost a 25% reduction
of the build time), and the final build directory weights 89 MB (a
reduction of almost 8%).
So, switching to a shared library only build brings some useful build
time and build size benefits.

This commit turns the single static option into a choice, which offers
various possibilities:
1. Build and use static libraries only;
2. Build both shared and static libraries, but use shared libraries;
3. Build and use shared libraries only.
On most platforms, (2) is currently the default, and kept as the
default in this commit. Of course, on certain platforms (Blackfin,
m68k), only option (1) will be available.
In addition to the introduction of the Config.in options, this commit
also:
* Removes the 'select BR2_STATIC_LIBS' from 'BR2_BINFMT_FLAT', since
with the use of a choice, we are guaranteed that BR2_STATIC_LIBS
will be selected when the binary format is BR2_BINFMT_FLAT, since
BR2_STATIC_LIBS will be the only possible solution in the choice.
* Changes package/Makefile.in to use the proper
--{enable,disable}-{shared,static} options for autotools packages.

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

This commit adds a Config.in option to the "Build options" submenu to
enable paranoid checking of unsafe paths. This mechanism is added as
an option so that when we'll enable it in the autobuilders, people
trying to reproduce the build failures will be able to do so by just
downloading the configuration file. If instead we were leaving this
feature as an environment variable, everyone would have to remember to
pass this environment variable to reproduce build issues. And certain
build issues triggered by paranoid unsafe patch checking may not be
visible in the build output, for example when they happen during the
execution of configure scripts.
Since this option is fairly advanced, a new submenu inside "Build
options" is created, for Advanced options.

Also, it seems to be more sensible to have local.mk alognside

Hence, change the default for BR2_PACKAGE_OVERRIDE_FILE to point to:

XBMC needs Java on the host in order to build, because it uses a

to parse C++ header files that define the API. SWIG outputs an XML file
that contains a complete description of the structure of the API. In the
second phase, the XML file is ingested by a Groovy (Java) program that then
creates C++ code that forms the bridge to the scripting language (Python).
The second phase is why we need java on the host.

In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.
A followup patch will make sure the overview is added to the list of

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

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.

Some bootloaders (such as Grub) need to be built for x86 (i.e IA32)
even if the target architecture is x86-64. However, when the target
architecture is x86-64, the cross-compiler generated by Buildroot is
not able to generate 32 bits code.
To solve this, we will rely on the host compiler being a x86 + x86-64
compiler. Therefore, this commit introduces the
BR2_HOSTARCH_NEEDS_IA32_COMPILER option, which tells the dependency
checking logic to verify that the host compiler is indeed capable of
building x86 32 bits code.

This commit refactors how Stack Smashing Protection support is handled
in Buildroot:
*) It turns the BR2_TOOLCHAIN_BUILDROOT_USE_SSP option into an option
that only enables the SSP support in uClibc, when using the internal
toolchain backend.
*) It adds an hidden BR2_TOOLCHAIN_HAS_SSP option that gets enabled
when the toolchain has SSP support. Here we have the usual dance:
glibc/eglibc in internal/external backend always select this
option, in the case of uClibc/internal, it gets selected when
BR2_TOOLCHAIN_BUILDROOT_USE_SSP is enabled, in the case of
uClibc/external, there is a new configuration option that the user
must select (or not) depending on whether the toolchain has SSP
support.
*) It adds a new options BR2_ENABLE_SSP in the "Build options" menu,
to enable the usage of SSP support, by adding
-fstack-protector-all to the CFLAGS.

At the Buildroot Developers Meeting (4-5 February 2013, in Brussels) a change
to the patch logic was discussed. See
http://elinux.org/Buildroot:DeveloperDaysFOSDEM2013
for details. In summary:
* For patches stored in the package directory, if
package/<pkg>/<version>/ does exist, apply package/<pkg>/<version>/*.patch,
otherwise, apply package/<pkg>/*.patch
* For patches stored in the global patches directory, if
$(GLOBAL_PATCH_DIR)/<pkg>/<version>/ does exist, apply
$(GLOBAL_PATCH_DIR)/<pkg>/<version>/*.patch, otherwise, apply
$(GLOBAL_PATCH_DIR)/<pkg>/*.patch
This patch adds the new BR2_GLOBAL_PATCH_DIR configuration item, and reworks
the generic package infrastructure to implement the new patch logic.

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.

Many users trying to use external toolchains on x86-64 machines get a
very confusing message:
"Can't execute cross-compiler"
They get this message because they forgot to install the 32 bits
compatibility libraries that are needed to run binaries compiled for
x86 on x86-64 machines.
Since this is the case for both external toolchains and certain
binary-only tools like SAM-BA, we add a new Kconfig option
BR2_HOSTARCH_NEEDS_IA32_LIBS, that packages must select if they need
the 32 bits compatibility libraries. When this option is enabled,
dependencies.sh checks that the 32 bits dynamic library loader is
present on the system, and if not, it stops and shows an error.
The path and name of the 32 bits dynamic loader is hardcoded because
it is very unlikely to change, as it would break the ABI for all
binaries.
Also, it is worth noting that the check will be done even if we're
running on a 32 bits machine. This is harmless, as 32 bits machines
necessarily have the 32 bits dynamic loader installed, so the error
will never show up in this case.

As discussed during the ELCE 2012 Buildroot Developers Meeting, we no
longer want to support the possibility of building a toolchain for the
target. None of the core developers have any use for this, it has been
known to be broken or cause problems for a long time without anyone
providing fixes for it.
In addition to this, Buildroot is inherently a cross-compilation tool,
so the usage of a native toolchain on the target is not really
useful. Many newcomers are tempted to use this possibility even though
it is clearly not the intended usage of Buildroot.

target/Config.in.arch had become too long, and we want to remove the
target/ directory. So let's move it to arch/ and split it this way:
* An initial Config.in that lists the top-level architecture, and
sources the arch-specific Config.in.<arch> files, as well as
Config.in.common (see below)
* One Config.in.<arch> per architecture, listing the CPU families,
ABI choices, etc.
* One Config.in.common that defines the gcc mtune, march, mcpu values
and other hidden options.

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.

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

This allows ccache to re-use its cache contents even if the compiler
binary mtime has changed. It is the simplest approach to solve this
problem, and it works for the internal, external and crosstool-ng
toolchain backends.
Of course, it leaves the user responsible for invalidating the cache
when necessary, but there doesn't seem to be a real good solution that
allows both to: 1/ keep the cache contents accross builds and re-use
it and 2/ invalidate the cache automatically when the compiler chances
in an incompatible way.
