[MIPS][X86] Updated to build X86 and to build MIPS correctly.

2. Updated Makefile: A. Now supports ARCH X86. B. Builds MIPS ARCH with _MIPS_SIM_ABI32: i) Was building with -D_MIPS_SIM=_MIPS_SIM_NABI32 to get around a problem with system call numbers not being defined for ABI32. Likely deserves a better fix.
