315b15109f libc/glibc: run ./configure in CONFIG_SHELL
Tremendously helps when running on at least Ubuntu, with dash as
the system shell (ie. /bin/sh points to dash).

5938837633 libc: remove unneeded glibc/eglibc common functions
do_libc_locales_extract() and do_libc_locales() in glibc-eglibc.sh-common have
been overridden for both glibc and eglibc, so they can now be removed, which
this patch does.

2ea05ecaa7 scripts/libc: do not build add-ons by default
Currently, no --enable-add-ons option is passed to libc configure when
"$(do_libc_add_ons_list ,)" is empty, which makes configure automatically search
for present add-ons. In that case, all present add-ons are built, although
no add-on was selected by the user in the config. Moreover, this can make the
configure fail if some non-standard add-ons like eglibc-localedef are present.

This behavior also leads to an inconsistency from a user point of view between
the following cases:
 - LIBC_ADDONS_LIST="", LIBC_GLIBC_USE_PORTS=n and THREADS="none" in the config,
   which makes "$(do_libc_add_ons_list ,)" return "", so all present add-ons
   are built.
 - LIBC_ADDONS_LIST="", LIBC_GLIBC_USE_PORTS=n and THREADS!="none" in the
   config, which makes "$(do_libc_add_ons_list ,)" return the add-on supporting
   the chosen threading implementation, e.g. "nptl", so only this add-on is
   built.

This patch disables the building of all add-ons in that case.

It is still possible to build all present add-ons by adding --enable-add-ons to
LIBC_GLIBC_EXTRA_CONFIG_ARRAY.

6940a6c0eb glibc: Refactor startfiles/headers into do_libc_backend()
Refactor the contents of 'do_libc_start_files()' and 'do_libc()' into a
parameterized 'do_libc_backend()'. 'do_libc_start_files()' and 'do_libc()'
call 'do_libc_backend()' with either 'libc_mode=startfiles' or
'libc_mode=final' (respectively) so that the startfiles/headers and
the final libc builds are configured and built with the same options.

One example of where this is needed is when building a mips toolchain.
Previously, if you were building an n32 toolchain, you wouldn't have
noticed an issue, because if '-mabi' is not in CFLAGS, n32 is the
default:

http://sourceware.org/git/?p=glibc-ports.git;a=blob;f=sysdeps/mips/preconfigure;hb=HEAD

But when trying to build an o32 or n64 toolchain the build would
have failed. This is because (e)glibc expects "-mabi={o32,n32,n64}" to be
in CFLAGS, but was not previously provided in 'do_libc_start_files()'.
The build failure would happen in the shared-core gcc when it tries to
configure an n64 or o32 gcc with an n32 libc.

A simpler solution would have been to just add TARGET_CFLAGS to configure
in 'do_libc_start_files()', but this way makes configure and make
consistent for both steps.

93b0db91b4 glibc: properly handle internal addons
Some addons are bundled with glibc/eglibc, so we should not try to
download and extract them.

This is done as thus:
 - at download time:
   - if the add-on download fails, keep going;
 - at extract time:
   - if the addon is present in the source tree, ignore it;
   - if the addon is missing in the source tree:
     - if the archive is present, extract it;
     - if the archive is missing, bail out.

b93e67f07c libc/glibc: add fortify option
By default, recent versions of glibc and eglibc will build some
functions that take format strings (eg. printf, syslog...) with
run-time checks against some format string attacks. This is
called a fortified build.

Unfortunately, this fails somehow while building the instrumented
version of syslog, with some kind of circular dependency...

Disable fortified builds by default, and hide the enabling option
behind EXPERIMENTAL for daring users...
