[Patch,MIPS] Add default SYS_futex definition in libgomp
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.
