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.
