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.

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.

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

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

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.

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.]

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.

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.

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.

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.
