PATCH: Check if RTLD_SAVESPACE_SSE is 32byte aligned

[H.J. Lu]

Hi,

Since sysdeps/x86_64/dl-trampoline.S has
 
	vmovdqa %ymm0, %fs:RTLD_SAVESPACE_SSE+0*YMM_SIZE

RTLD_SAVESPACE_SSE must be 32-byte aliged.  This patch adds a compile
time check.  Tested on Linux/x32 and Linux/x86-64.  OK to install?

Thanks.

H.J.
