[OE-core] [PATCH] libffi: Make it build for MIPS o32

[Peter Kjellerstedt]

This solves the following errors:

  src/mips/o32.S: Assembler messages:
  src/mips/o32.S:286: Error: opcode not supported on this processor:
    mips32r2 (mips32r2) `s.d $f12,((16*4)-10*4)($fp)'
  src/mips/o32.S:287: Error: opcode not supported on this processor:
    mips32r2 (mips32r2) `s.d $f14,((16*4)-8*4)($fp)'
