[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.

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

3. Disabled Vi use of signals:

   A. X86 librarys are missing siglongjmp() and sigsetjmp() symbols
      in android-ndk-r8b. Simply disabled for arm, x86, and mips for now.
      Expect a new NDK shortly. Not a problem for arm and mips.
