tilegx warning

[Alan Modra]

gcc-4.6.1 isn't clever enough to see that mask really can't be used
uninitialised.
.../elfxx-tilegx.c: In function ‘tilegx_elf_relocate_section’:
.../elfxx-tilegx.c:3287:28: error: ‘mask’ may be used uninitialised in this function [-Werror=uninitialized]

	* elfxx-tilegx.c (tilegx_elf_relocate_section): Silence bogus warning.
