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:

 ldso/mips: workaround for missing TLS macros in elfinterpret.c

 These macros declarations are missing, so gcc believes the code is calling

 a function, so any later linking will fail.

 Work this around by copying the mcaros from:

    libpthread/nptl/sysdeps/mips/dl-tls.h

 We can't include the header because of incompatible symbol declarations,

 so we just copy the macros for now.
