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 gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-4.1-alpha-mieee-default.patch

 Set the default behavior on alpha to use -mieee since the large majority of

 time we want this (bad/weird things can happen with packages built without

 -mieee).

 To satisfy those people who may not want -mieee forced on them all the time,

 we also provide -mno-ieee.
