Bugzilla Bug 49472

Well, subject says it all. Some assembler error about a value not fitting will
occur if down cflags are used in conjunction with -ftracer. Intrestingly same
setup with march=athlon-xp works. A compiler issue?

FOr the time beint -ftracer should be filtered in case of gcc-3.4 and
-march=k6-2.

*bump* news on this?

This is still a problem with gcc-3.4, but is fixed in gcc-4.  I added filtering
for -ftracer to the libvorbis ebuilds.
