+       [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-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)
