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.

Now there are two rsyncs, but with different filter specs, which
seems odd.

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.

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.

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.

* 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

As a consequence, this patch also removes target/Makefile.in, which

The architecture tuple is 'aarch64', but the kernel people decided to
call it 'arm64', so we have to do some mungling to get the kernel
architecture name from the Buildroot architecture name.

The pkgconfig files are located in /usr/lib/pkgconfig
and /usr/share/pkgconfig directories.
However, only /usr/lib/pkgconfig is removed when no
development files are needed in the target filesystem.
Remove pkgconfig directory from $(TARGET_DIR)/usr/share
as well if BR2_HAVE_DEVFILES is not set.

As stated in commit 555c2585bf, the
Xtensa architecture has been introduced in 2009 and never changed
since its initial introduction. It requires some special handling that
is a bit annoying, and despite our call to the initial developers, and
the announcement of the deprecation of the architecture during the
2012.05, nothing has happened. Therefore, drop support for this
architecture.

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.

If PKG_CONFIG_PATH is set in the environment, it allows pkg-config to
look for libraries outside of the buildroot tree. This is a problem
both for host and target builds. To avoid it, globally set an empty
PKG_CONFIG_PATH in the environment.

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'.
[Peter: removed source-check-all, people can just make allyesconfig before]

Sometimes it may be desirable to keep debug symbols for some binaries and
libraries on the target. This commit introduces the config option
BR2_STRIP_EXCLUDE_FILES, which is interpreted as a list of such binaries
and libraries, and the option BR2_STRIP_EXCLUDE_DIRS, which indicates
directories excluded from stripping entirely.
These exclusions are passed to the find command in the target-finalize step.

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.

So that this works:
% make defconfig BR2_DEFCONFIG=~/buildroot-defconfig
Right now we have to do:
% cp ~/buildroot-defconfig configs/buildroot_defconfig
% make buildroot_defconfig
That would dirty the buildroot tree and requires it to be writable.

There used to be a mechanism using which packages could leave a
.fakeroot.<something> file which could contain commands to be executed
within the fakeroot environment. Since this mechanism is no longer
used by any package, remove it from the common infrastructure.
The latest user was nfs-utils, which used this mechanism to do the
"make install" as root, since doing otherwise was not supported. But
since 16e7b8255c, nfs-utils has been
upgraded and converted to the package infrastructure, and this hack is
no longer necessary. Another past user was the ltp-testsuite package,
for the same reason, and since
a72a670489, the fakeroot hack is no
longer needed.
