I believe this is the controlling bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1510073. Or it is the
controlling issue for Fedora. It may apply to Red Hat as well.

I'm less clear on the fix. It seem's like Fedora's
/usr/share/config.site should properly handle --prefix=/usr/local and
libdir, without the need to add a /usr/local/share/site.config or the
need to RTFM. That is, Fedora's site.config should "just work".
