SYSTEM_HEADER_DIR can also depend on the multilib, so the logic testing 
for tgmath.h would best go in the loop over multilibs that runs 
LIMITS_H_TEST.  This would mean tgmath.h goes in include-fixed rather than 
include (which agrees with where I said it should go when include-fixed 
was first proposed <http://gcc.gnu.org/ml/gcc/2004-11/msg00255.html>).
