Here is another patch for the MIPS android build.  It is in the libgomp
subdirectory and it has been in the Android tree for a while but I would
like to check it in to the official GCC tree so we do not need to keep
porting it to new versions of GCC.

This patch defines SYS_futex if it is not already defined and the same type
of define is already in the x86 and alpha futex.h header files in libgomp.

Tested on mips-mti-linux-gnu and mips android builds.  OK for checkin?
Since this is bug fix (inability to build on android) I think it qualifies
under the stage 3 rules.

	* config/linux/mips/futex.h (SYS_futex): Define if not already done.
