GCC's notion of host vs build is backwards.  It's a pain in the butt.  Fixing
it was discussed a while ago, and if I remember right the decision was not to
mess with it (it had some value, but I can't remember what it was).

It's entirely possible we've further confused things by using the normal
host vs build conventions somewhere (if so, we ought to fix that :-)

Are you missing a case where you need to add gansidecl.h to build_xm_file_list
in the last hunk in the outer else arm?
