Request for Feedback

[Marcus Calhoun-Lopez]

I have created a new PortGroup to test possible changes to the base
code concerning compiler selection.
See https://trac.macports.org/ticket/55139.
I would greatly appreciate feedback from anyone knowledgable and/or
interested in compiler selection.

In the short term, the new PortGroup could be used to solve issues like
https://trac.macports.org/ticket/52468.

Thanks,
Marcus
