A bit complicated, no?

Also, how does one get binaries built with the resulting compilers to use the
corresponding runtime libraries (libstdc++, libgfortran, ...)? There should be
a configure option for that too, IMHO, possibly even a single option.

Sidewise related: I configured with `--with-libdir=/opt/local/lib/gcc7`,
thinking I'd get the runtime libraries installed there. This is the case on
Mac, but on Linux I discovered libstdc++ and family in /opt/local/lib/lib64
instead.

That kind of surprise doesn't make it easy for the end-user to add an explicit
rpath option.
