[BZ #758]
* sysdeps/unix/sysv/linux/mips/configure.in (asm-unistd.h): Only
preprocess <asm/unistd.h> if it defines ABI-prefixed syscall names
like __NR_N32_open. Just include <asm/unistd.h> otherwise.
* sysdeps/unix/sysv/linux/mips/configure: Regenerate.
* sysdeps/unix/sysv/linux/mips/mips32/kern64/sysdep.h: Delete
* sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h (SYS_ify): Use the
standard __NR prefix.
* sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h (SYS_ify): Likewise.
* sysdeps/unix/sysv/linux/mips/Makefile (syscall-%.h): Rework so that
the output file is compatible with both pre-2.6 and 2.6 kernel headers.
Extract separate syscall lists for each ABI.
* Makerules: Always use -MP together with -MD.
(sed-remove-dotot): Substitute $(..) also at start of line.
($(stdio_lim:h=st)): Use -MD instead of SUNPRO_DEPENDENCIES.
Generated defines with a single compiler call.
Use $(sed-remove-dotdot).
* mach/Makefile ($(objpfx)mach-syscalls.mk): Use -MD instead
of DEPENDENCIES_OUTPUT, and use $(sed-remove-objpfx).
* sysdeps/unix/sysv/linux/Makefile ($(objpfx)syscall-%.h):
Use -MD instead of SUNPRO_DEPENDENCIES, and use $(sed-remove-objpfx).
* sysdeps/unix/sysv/linux/mips/Makefile
($(objpfx)syscall-%.h): Likewise.
asm/unistd.h into asm-unistd.h.
* sysdeps/unix/sysv/linux/mips/configure: Generated.
* sysdeps/unix/sysv/linux/mips/Makefile: Do custom processing
of syscall list.
* sysdeps/unix/sysv/linux/mips/sys/syscall.h: New file.
* sysdeps/unix/sysv/linux/mips/clone.S: Don't include
asm/unistd.h.
