Revert "kbuild: fix modpost segfault for 64bit mipsel kernel"

This reverts commit c8d8b837ebe4b4f11e1b0c4a2bdc358c697692ed, which
caused problems for the x86 build. Quoth Sam:

  "It was discussed on mips list but apparently the fix was bogus.  I
   will not have time to look into it so mips can carry this local fix
   until we get a proper fix in mainline."
