Based on the difference you posted, I'm guessing the trouble is not
with fixincludes itself but all the gunk surrounding it.  Your -j
build saw two different versions of stddef.h, which is not fixed, it's
copied from src/gcc/ginclude.  Look at stmp-int-headers and its

My understanding of the sequencing here is that build/include is
supposed to be created once, after the stage1 cc1 and xgcc are built
but before they are used to build anything.  It sounds like it is
getting recreated part way through stage2, which would be wrong.
