Siddhesh Poyarekar 6482e63403 Add include guards to dl-procinfo.h
The dl-procinfo.h for linux/s390 and linux/i386 don't have include
guards, which causes them to fail since addition of LD_HWCAP_MASK to
tunables.  Add _DL_I386_PROCINFO_H guard to avoid redefining
_dl_procinfo on multiple includes and also allow the subsequent
include of another dl-procinfo.h to work.

Verified with a build test on i686.

	* sysdeps/unix/sysv/linux/i386/dl-procinfo.h: Add include
	guard.
	* sysdeps/unix/sysv/linux/s390/dl-procinfo.h: Likewise.
