arch: add option to disable internal toolchain backend

Some architectures or specific cores do not have support in upstream
gcc. Currently, they are individually listed as exclusions in the
toolchain choice.

This poses a maintainance burden, as the knowledge about what gcc
version supports what architecture is split across many places: the
toolchain choice, the gcc version choice, the external toolchains.

As a first step, add a blind option that architectures or individual
cores may select to indicate they lack support in our internal backend.

Actual use of the option will come in followup patches.

flex: Fix segfault of stage1flex when host has glibc 2.26 or newer

When the host uses glibc 2.26 or newer, Flex will try to use the
newly-introduced reallocarray() function, but as it would not define
_GNU_SOURCE a segmentation fault would occur later on due to the
compiler assumming that the function is implicitly defined.

This issue manifests itself due to a crash of "stage1flex" during the
Flex bootstrap:

  ./stage1flex   -o stage1scan.c ./scan.l
  make[2]: *** [Makefile:1725: stage1scan.c] Segmentation fault (core dumped)

This imports the patch from the upstream Git repository, and adds flags
in the .mk file to rebuild the Autotools scripts and support files. Due
to the latter, the patch to disable the documentation is changed so it
modifies the .am file instead.

package/asterisk: fix host build

The host menuselect tool is linked to our host libxml2 library, but it
is missing an RPATH to the host directory.

This is because menuselect does not use automake, so does not inherit
the LDFLAGS from the configure run.

We fix that by simply passing $(HOST_CONFIGURE_OPTS) in the make
environment.

At the same time, we also install the tool in the host directory, even
if not used from there, so that the sanity checks we run are properly
passed.

support/check-rpath: recognise PIE

We sanity-check the host executables that they have a correct RPATH
pointing to the host libraries.

This is currently done by looking for all files in $(HOST_DIR) that
match the 'ELF executable' pattern (a bit more complex, but that's
idea).

However, when an executable is built with -fPIE of -fpie, it no longer
appears to be an 'ELF executable', but it rather looks like an 'ELF
sheard object' (like if it were an library.

So, we miss those files.

It turns out that the problem is a real one, because quite a few
mainline distros, expecially those based on Debian for example, have
already switched to generating PIE code by default, and thus we miss on
a whole class of systems..

We fix that by simply looking if we can find an ELF interpreter in each
file. If we there is one, this is an ELF executable; if not, it may be
anything else: we don't care (not even about ELF libraries).

nginx (S50nginx): Fix stop, reload, restart. Add force-reload.

Fix package/nginx/S50nginx:

* On stop, use start-stop-daemon -R 1 to wait for the nginx processes
  to actually stop.  This fixes a race condition with restart, where
  nginx fails to restart because start is called too early
  w.r.t. stop.  (This only works with Debian's start-stop-daemon,
  however BusyBox's start-stop-daemon does not fail when given -R; it
  just ignores the argument silently).
