[CT-NG:patch 05/19] Force autoreconf for mpfr

In some exotic case the autoreconf step of mpfr is not executed (correctly)
leaving an incorrect version number for libtool in the configure script.

After extracting the sources files, force autoreconf to be executed.

complibs: save directory with static complibs for stop/restart

complibs: don't install in toolchain dir when built as static

complibs: allow either static or shared build

complibs: build static libraries

config: replace COMP_LIBS with COMPLIBS

complibs/mpfr: fix extract

With MPFR 2.4.2, autoreconf needs to be run as well.

scripts: add script to publish patches

This script creates the patches for an existing version.

Re-enable the FD_PIC ELF configuration option

Blackfin uses FD_PIC ELF format to provide shared libraries on a
non-MMU architecture.

Fix the uClibc clean-up-O_CLOEXEC-handling patch

In the Blackfin case (untested until now), this patch was lacking a
leading / at the end of a comment.

scripts/populate: fix handling the forced libraries list-file

If a list-file is used, then each library in the file will be handled
twice (not a real issue, as the second iteration will find the library
already present, just avoid doing the job twice).

cc/gcc: fix thread-less final gcc build

If threads are disabled in libc, we don't want to enable them in the
final compiler. Doing so pass the configure stage, but fails latter on
a missing <pthread.h>.

Moreover, we don't want to build libgomp if threads are disabled; its
configure script would fails anyway.

config: allow libc selection in backend mode

In backend mode, allow the upper-layer build system to force the
C library selection.

config: do not force setting kernel and arch

In backend mode, only enforce the arch and/or kernel selection if the
upper-layer build system effectively forces the selection.

scripts: misc help and auto-complete fixes

- don't list samples in the main help screen
- improve the samples listing in list-samples
- don't document the 'config' action, it's long dead
- document the 'V' environment variable
- improve on START, STOP and PREFIX environment variables
- add PREFIX and V to autocomplete
- advertise auto-complete at install time

config: fix style issues when source-ing files

Always enclose the sourced file between double-quotes (purely for
consistency; enclosing or not are both allowed by the kconfig language).

config: move backend-related options to their own file

config: hide arch and kernel selection when used as a backend

When used as a backend, it is the responsibility of the upper-layer build
system to set the target architecture and kernel.

config: hide options to debug crosstool-NG when a backend

When used as a backend, it does not make sense to debug crosstool-NG,
so hide the option.

config: hide more config options when a backend

Hide the prompts for some behavioral options, for which the upper-layer build
system is responsible for:
- parallel jobs and maximum load
- use pipes
- use custom shell
