tile: align stack for tilegx32
Previously we weren't re-aligning the stack pointer during the
call to _dl_init(), so for tilegx32 and an odd value in _dl_skip_args
and kernel unaligned access fixups disabled, we would die with SIGBUS.
We now handle this case properly by aligning before calling _dl_init().
