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.

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.

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.

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

Then "grep -qx $${langdir##*/}" ungoes two shell expansions (how?)
that transform the expression from "${langdir##*/}" to "*" to "list of

After the linux upstream commits 5ef7bbb09f7b ("perf tools: Allow to
specify custom linker command") and 3c71ba3f80bb ("perf tools: Really allow

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

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.

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.

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.

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.

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.
