[gentoo-dev] FEATURES=test, sys-devel/gcc ignored test failures

sys-devel/gcc runs tests, but the results are ignored and I remember the
tests fail most of the time.

Because the tests take long time to run and fail anyway (I understand
it's non-trivial to fix those on Gentoo side), I wonder whether it makes
sense to run them at all:

toolchain.eclass:

gcc_src_test() {
    cd "${WORKDIR}"/build
    emake -j1 -k check || ewarn "check failed and that sucks :("
}

My suggestion is to make the src_test empty (I think the default one
still calls make). I can produce a patch if needed.

What do you think?
