[BZ #20729]
Support i386 builds with CFLAGS which imply -fno-omit-frame-pointer.
* sysdeps/unix/sysv/linux/i386/Makefile
(uses-6-syscall-arguments): Define.
[subdir == misc] (CFLAGS-epoll_pwait.o, CFLAGS-epoll_pwait.os)
(CFLAGS-mmap.o, CFLAGS-mmap.os, CFLAGS-mmap64.o, CFLAGS-mmap64.os)
(CFLAGS-pselect.o, CFLAGS-pselect.os, CFLAGS-rtld-mmap.os): Use it.
[subdir = sysvipc] (CFLAGS-semtimedop.o, CFLAGS-semtimedop.os):
Likewise.
[subdir = io] (CFLAGS-posix_fadvise64.o, CFLAGS-posix_fadvise64.os)
(CFLAGS-posix_fallocate.o, CFLAGS-posix_fallocate.os)
(CFLAGS-posix_fallocate64.o, CFLAGS-posix_fallocate64.os)
(CFLAGS-sync_file_range.o, CFLAGS-sync_file_range.os)
(CFLAGS-fallocate.o, CFLAGS-fallocate.os, CFLAGS-fallocate64.o)
(CFLAGS-fallocate64.os): Likewise.
[subdir = nptl] (CFLAGS-pthread_rwlock_timedrdlock.o)
(CFLAGS-pthread_rwlock_timedrdlock.os)
(CFLAGS-pthread_rwlock_timedwrlock.o)
(CFLAGS-pthread_rwlock_timedwrlock.os, CFLAGS-sem_wait.o)
(CFLAGS-sem_wait.os, CFLAGS-sem_timedwait.o)
(CFLAGS-sem_timedwait.os): Likewise.
