* sysdeps/unix/sysv/linux/mips/Makefile ($(objpfx)syscall-%.h):
	Sort by syscalls.  Make sure we get headers such as sgidefs.h from
	the build tree before just-installed ones.

	* sysdeps/mips/atomicity.h, sysdeps/mips/dl-machine.h,
	sysdeps/mips/machine-gmon.h, sysdeps/mips/bits/setjmp.h,
	sysdeps/mips/fpu/bits/mathdef.h,
	sysdeps/mips/mips64/__longjmp.c,
	sysdeps/mips/mips64/setjmp_aux.c,
	sysdeps/unix/sysv/linux/mips/kernel_stat.h,
	sysdeps/unix/sysv/linux/mips/pread.c,
	sysdeps/unix/sysv/linux/mips/pread64.c,
	sysdeps/unix/sysv/linux/mips/ptrace.c,
	sysdeps/unix/sysv/linux/mips/pwrite.c,
	sysdeps/unix/sysv/linux/mips/pwrite64.c,
	sysdeps/unix/sysv/linux/mips/sigaction.c,
	sysdeps/unix/sysv/linux/mips/sigcontextinfo.h,
	sysdeps/unix/sysv/linux/mips/bits/fcntl.h,
	sysdeps/unix/sysv/linux/mips/bits/sigcontext.h,
	sysdeps/unix/sysv/linux/mips/bits/stat.h,

	sysdeps/unix/sysv/linux/mips/sys/ptrace.h,
	sysdeps/unix/sysv/linux/mips/sys/tas.h,
	sysdeps/unix/sysv/linux/mips/sys/ucontext.h,
	sysdeps/unix/sysv/linux/mips/sys/user.h: Use standard names
	for ABI macros, include sgidefs.h where appropriate.
	sysdeps/unix/sysv/linux/mips/Makefile ($(objpfx)syscall-%.h):
	Likewise.
	sysdeps/unix/sysv/linux/mips/configure.in (asm-unistd.h):
	Likewise.
	sysdeps/unix/sysv/linux/mips/configure: Rebuilt.
