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."
