4802db3dad core: introduce a generated kconfig snippet
Add the infrastructure for adding generated kconfig snippet in the
menuconfig.

For now, the kconfig snippet is generated empty, the recipe for filling
it in will be introduced in sub-sequent patches.

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.)

Use rsync with '--keep-dirlinks' option to prevent rootfs overlay to
overwrite /usr, /bin, /sbin and /lib links in case BR2_ROOTFS_MERGED_USR
option is enabled.

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.

2658b82353 Revert "core: add the possibility to provide help for custom rules"
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
variables are inherited from the environment.
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.

50a93866f0 skeleton: move LIB_SYMLINK definition from Makefile
Commit 7a6b83a211 introduced the skeleton
package, which took over the lib32/lib64 -> lib symlink creation from the
main Makefile.
However, the definition of the LIB_SYMLINK variable did not move along, for
no real reason.

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.

[Peter: use HOSTCC_NOCCACHE]

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.

12825f7af5 Config.in: add symbols for BR2_HOST_GCC_AT_LEAST_X_Y
Some host packages need a recent gcc version. Add symbols to Config.in
to specify the HOSTCC version. The values are passed through the
environment, and this environment is generated in a new support script.

Also update the documentation to mention the new symbols.

[Thomas: simplify by using only make logic instead of an external
shell script.]

1edb4c51de Makefile: valgrind needs non-stripped dynamic linker library
Fixes the following valgrind error (tested on freescale imx6):

valgrind:  Fatal error at startup: a function redirection
valgrind:  which is mandatory for this platform-tool combination
valgrind:  cannot be set up.  Details of the redirection are:
valgrind:
valgrind:  A must-be-redirected function
valgrind:  whose name matches the pattern:      strcmp
valgrind:  in an object with soname matching:   ld-linux-armhf.so.3
valgrind:  was not found whilst processing
valgrind:  symbols from the object with soname: ld-linux-armhf.so.3
valgrind:
valgrind:  Possible fixes: (1, short term): install glibc's debuginfo
valgrind:  package on this machine.  (2, longer term): ask the packagers
valgrind:  for your Linux distribution to please in future ship a non-
valgrind:  stripped ld.so (or whatever the dynamic linker .so is called)
valgrind:  that exports the above-named function using the standard
valgrind:  calling conventions for this platform.  The package you need
valgrind:  to install for fix (1) is called

Note that we can still strip the dynamic linker, but only strip the
debugging symbols and nothing else.

[Thomas: slightly adjust comment in the code.]
