I'm not sure how much we care about this or what we can do about it, but
adding the macros.s to the command line like this has effectively broken
distributed compiling with distcc and icecc as of v4.20-rc1. Neither
tool will successfully distribute any compile processes because the
non-local machines won't have a copy of macros.s.

Thanks,

Logan
