Someone shoot me (figuratively speaking only).  I'm fairly sure that
this is related to the patch I installed earlier today where I
propagate HOST_CC from stage 1 to later stages.  Obviously (to me now
in light of your findings), one must propagate all HOST_ variables
that might be recomputed in a submake if we pass any of them...  I
wonder how one is suppose to determine that complete set without any
trial and error.  Or, should they all be propagated without study?

To fix the problem David uncovered, I need input from the
gcc/Makefile.in gurus.  Here is the full thread on the broken (or
half-complete) patch:
