 I have found out that I can install thoose older comilers with:

FEATURES="-sandbox -usersandbox" emerge -aqv   =sys-devel/gcc-5.4.0-r4

# since ustat.h is no loger with (>=glibc 2.28) according to 
# https://sourceware.org/git/?p=glibc.git;a=commit;h=cf2478d53ad7071e84c724a986b56fe17f4f4ca7
echo =sys-devel/gcc-4.9.4 -sanitize >> /etc/portage/package.use/gcc
eselect gcc set 1
. /etc/profile
FEATURES="-sandbox -usersandbox" emerge -aqv   =sys-devel/gcc-4.9.4

gcc-3.4.6-r2 still doesn't install though.
