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:
