Hmm, I've been playing with a fix for gcc/Makefile.in that may be related.
The problem is that the stage makes don't get passed any flags and so
(wrongly?) fallback to the defaults. I added $(ORDINARY_FLAGS_TO_PASS) to
all of them. It fixes the variable passing problems I encountered, but I
did only native builds/bootstraps so far.
Franz.
