[PATCH] Fix s390x tst-tls* when built with GCC 3.4+

Hi!

GCC 3.4+ on s390x no longer considers r14 to be a fixed register, so we need
to tell the compiler we are clobbering it, otherwise GCC puts vital
temporaries in it and they get clobbered by the TLS_{LD,GD} macros.
I have built tst-tlsmod2.c with this patch even with GCC 3.3 and it built
just fine.

	* elf/tls-macros.h [__s390x__] (TLS_LD, TLS_GD): Clobber also r14.
