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:

     Rules.mak: Rearrange appending UCLIBC_EXTRA_CFLAGS to CFLAGS

     UCLIBC_EXTRA_CFLAGS is currently added before the OPTIMIZATION flags

     and OPTIMIZATION is chosen to be Os by default. But in OE we pass the optimisation

     flags through UCLIBC_EXTRA_CFLAGS but they are not effective since -Os is

     specified at last. So we need to change the order of these option flags
