On some architectures (namely x86-64), glibc may provide a libmvec
library since glibc 2.22, which programs built with gcc OpenMP support
might get linked to.
In order for these programs to work on the target, we need to copy
this library to the target filesystem.
This commit takes care of this for the external toolchain
situation. Note that libraries listed in TOOLCHAIN_EXTERNAL_LIBS are
silently ignored if they don't exist. Therefore, we don't need to have
any condition on the architecture or glibc version.
For more details on libmvec, see
https://sourceware.org/glibc/wiki/libmvec.
Fixes bug #9111.

Some packages misbehave, and install files in either $(STAGING_DIR)/$(O)
or in $(TARGET_DIR)/$(O) .
One common reason for that is that pkgconf now prepends the sysroot path
to all the paths it returns. Other reasons vary, but are mostly due to
poorly writen generic-packages.
And a new step hooks to check that no file gets installed in either
location, called after the install-target and install-staging steps.

perl may fail to build on newer host architectures such as aarch64 due
to its inability to guess the host architecture to build 'miniperl',
which is built during the process. An error message looks like this:
Configuring build-time miniperl for unknown
ERROR: No $target defined (?!)
ERROR: configure --mode=buildmini failed
This happens because the config.sub and config.guess files from perl are
not modified and may become outdated.
These files are normally updated automatically by a Buildroot hook for
autotools packages, to avoid problems like these.
Although perl uses the config.sub and config.guess files, it is not a
strict autotools package, so it is not defined as an "autotools-package"
in Buildroot and so it doesn't inherit the hook.
This commit makes perl borrow the hook from the autotools infrastructure
so that it can build on newer build architectures.
This has been tested by building it on an aarch64 host machine.

We can avoid host headers using a --with-libnl parameter to override the
default host headers path. The configure script adds /include suffix to the
include path. So we still need to manually add -I with the correct path to
CFLAGS because libnl headers are under the libnl3/ directory.

On x86 (both i386 and x86_64), the kvm-unit-tests code uses
__builtin_reachable, which appeared in gcc 4.5. This commit adds the
relevant dependencies to kvm-unit-tests:
- on i386, we need gcc 4.5 as the target compiler
- on x86-64, we need gcc 4.5 as the host compiler, because we use the
host compiler to build kvm-unit-tests for this architecture

kvm-unit-tests requires a multilib compiler for x86_64 as it compiles
32bit boot code.
This patch uses the BR2_HOSTARCH_NEEDS_IA32_COMPILER option to enforce
this and avoids using TARGET_CROSS for x86_64 targets and uses the host
32bit (and 64bit) capable compiler.

lib/colors.c uses HAVE_LIBTINFO to decide whether term.h and ncurses.h
should be included. However, the configure.ac check is bogus: it
checks for tinfo using pkg-config, and then if it fails, checks with
AC_CHECK_LIB(). So, if you have tinfo installed, but not the
corresponding development package, the pkg-config test will fail, but
the AC_CHECK_LIB test will succeed, even though the headers are not
available.
To address this, we explicitly tell host-util-linux that tinfo is not
available, like we're already doing for ncurses.

Currently, there are two failure paths in the wrapper:
- if the tar fails, then the error is ignored because it is on the
left-hand-side of a pipe;
- if the find fails, then the error is ignored because it is a
process substitution (and there is a pipe, too).
While the former could be fixed with "set -o pipefail", the latter can
not be fixed thusly and we must use an intemediate file for it.
So, fix both issues by using intermediate files, both to generate the
list of files to include in the archive, and generate the archive in a
temporary tarball.
Fixes the following build issue, where the find is failing for whatever
unknown reason:
http://autobuild.buildroot.net/results/20f/20fd76d2256eee81837f7e9bbaefbe79d7645ae9/
And this one, where the process substitution failed, also for an unknown
reason:

Now that we can dump the reverse dependencies of a package, add the
ability to graph those.
It does not make sense to do a full reverse graph, as it would be
semantically equivalent to the direct graph. So we only provide a
per-package reverse graph.

Finding the packages that select another one in a specific configuration
is not very trivial:
- when optional, the dependency is not expressed in Kconfig
- looking at the .mk files is not very nice.
Introduce a way to dump reverse dependencies of packages, i.e. the list
of packages that directly depend on that package. Like for direct
dependencies, we limit the list to the first-order reverse dependencies.
Document it in the main help; use the opportunity to also document
foo-show-depends.
