libc/eglibc: fix localedef 2.14 build

The localedef of eglibc 2.14 requires NOT_IN_libc to be defined in order to
compile intl/l10nflist.c.

This is because localedef is built separately from eglibc and uses some parts of
eglibc that don't compile in standalone without this preprocessor definition.

This fixes the following error:

Original patch from: ../4.3.2/110-trampolinewarn.patch

-= BEGIN original header =-

Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-trampolinewarn.patch

	This trivial patch causes gcc to emit a warning whenever

	it generates a trampoline.  These are otherwise hard to

	locate.  It is rigged to default ON - to have it default

	to OFF remove the text 'Init(1)' from the common.opt

	patch, leaving just 'Common Var(warn_trampolines)'.
