My main point here would be that we are already setting this for all
extensions for sparc and sparc64, so s390(x) would just follow suit.
-fPIC is the default in Debian now, see the discussion starting at
https://lists.debian.org/debian-devel/2016/05/msg00028.html
including the Fedora: https://lists.debian.org/debian-devel/2016/05/msg00219.html
and Ubuntu: https://lists.debian.org/debian-devel/2016/05/msg00225.html
situation, which all do that.
