Have you tried it with the updated ebuild (by SpanKY) at 
http://bugs.gentoo.org/attachment.cgi?id=43893 ? I'm not completely sure 
what it actually does, but it looks a bit like it alters CFLAGS in 
Rules.mk and a few other Makefiles to pick up the environment's CFLAGS:
        sed -i \
                -e "/CFLAGS/s:-O3:${CFLAGS}:" \
                tools/libx{c,util}/Makefile \
                tools/misc/{miniterm,nsplitd}/Makefile \
                tools/{misc,xentrace}/Makefile \
                xen/arch/x86/Rules.mk || die "sed cflags"
