As of MacPorts 2.4.3, macports-gcc-6 and macports-gcc-7 are already in the fallback list, so this line is unnecessary and should be removed.

The problem is that the cxx11 1.1 portgroup uses "compiler.whitelist macports-gcc-6", which means that it cannot use any other compiler. This was done before MacPorts 2.4.3 -- before MacPorts base knew about using macports-gcc. The portgroup needs to be changed to use compiler.blacklist instead of compiler.whitelist.
