On principle, most things in the tree should respect whatever CFLAGS,
LDFLAGS, etc. you ask for. The problems resulting from that are
predictable: if you add "-ffast-math" to your CFLAGS and then start
getting crashes; well, you asked for it. We're not going to fix that for
you in every ebuild.
On the other hand, there are packages where some optimizations fail due
to a compiler bug or something else that is not by design. Some packages
optimize their critical path in assembly, and the resulting code doesn't
play well with otherwise-reasonable CFLAGS. In cases like those, it's
often simpler to disable the problematic flag in the ebuild rather than
have a thousand people do the same thing locally.
