libc/uClibc: workaround for a MIPS TLS issue

Browse Source 
Some macros declarations were missing, so we duplicate them.
See the added patch description for more information.

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.
