MIPS: SB1: Fix excessive kernel warnings.
A kernel build with binutils 2.24 is going to emit warnings like CC kernel/sys.o {standard input}: Assembler messages: {standard input}:701: Warning: the 32-bit MIPS architecture does not support the `mdmx' extension {standard input}:701: Warning: the `mdmx' extension requires 64-bit FPRs {standard input}:701: Warning: the `mips3d' extension requires MIPS32 revision 2 or greater {standard input}:701: Warning: the `mips3d' extension requires 64-bit FPRs for almost every file. This is caused by changes to gas' interpretation of .set semantics. Fixed by explicitly disabling MIPS3D and MDMX for Sibyte builds. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
