I think it does, but I worry that I'm missing some oddity in
yum/dnf/mock parsing of the single config file.  I tested
with mock-1.4.8 on Fedora 26.  Moving the epel repo section
after the sclo* repos I was still able to install epel
packages.  I was worried that the includepkgs might not be
properly limited to the sclo repos, but it seems like it is.
It's easy enough to remove it if that proves incorrect with
wider testing.

Yeah, I imagine we're at the point where most people
building things which require a newer compiler are moving to
EL-7.  I could have used it while trying to build znc-1.6
for EL-6 a year or so ago.

(I ended up building znc with clang instead.  I was going to
send the patch to the znc maintainers in EPEL, but it got
dropped in EL-6 before I had time to do so.)
