As far as I can see SCL & devtoolset are not available for CentOS 8 -
the toolsets are integrated as part of the main distro, and they are
only for newer versions of GCC and not older ones.

Yes, you are trying to install a CentOS7 package on CentOS8. It
probably won't work.

It depends what it is about GCC v6 you need - you can control the
dialect of C that GCC act as using the '-std='. Ultimately though,
just download that particular version of GCC and compile/install it,
it's not a difficult thing to do and most of it is automated.
Strangely though, GNU doesn't seem to think that 6.3.1 exists, the
nearest on the GCC downloads is 6.3.0.
