updated workstations setup breaks FC27

[andrewboie]

The gcc-c++.i686 package is causing problems.

When I first installed it:

$ sudo dnf install gcc-c++.i686

It downgraded GCC from 7.3 to 7.2!

Now when I try to update my system:

$ sudo dnf update

This appears to be a Fedora issue so filing an upstream bug is sufficient to close this.
