Pull x86 build bits from Peter Anvin:
 "Various build-related minor bits.

  Most of this is work by David Woodhouse to be able to compile the
  early boot code with clang/llvm; we have also managed to push an
  actual -m16 option into gcc 4.9 so this makes us use that option if
  available instead of hacking it.

  The balance is a patch from Michael Davidson to the relocs program to
  help manual debugging.

  None of these should change the actual compiled binary with currently
  released compilers"
