What is the general solution for this problem? Is there a non-gcc

No there is currently no clang version of Fortran. 'flang' was a SOC project
to bring in clang support for fortran but it is moribund. The
clang guys are the ones you should bug. In any case, the Fortran spec
now requires quad math support so that would have to be provided as well.
One thing is when gcc is required because clang can't compile something,
and another things is when fortran language requires it. The latter is
here to stay.
Can there be the separate fortran from gcc that is build with clang? Or
can we switch /usr/ports/lang/gccNN to be always built with the base
clang? I know this is certainly possible.
No. The core problem is due to our version of libgcc not having quadmath
support.
Maybe the quadmath files could be taken out to make a standalone library.
Another possibility might be DragonEgg, though it doesn't appear to
have been updated for a while.

"DragonEgg is a gcc plugin that replaces GCC's optimizers and code
generators with those from the LLVM project. It works with gcc-4.5 or
newer, can target the x86-32/x86-64 and ARM processor families, and has
been successfully used on the Darwin, FreeBSD, KFreeBSD, Linux and
OpenBSD platforms. It fully supports Ada, C, C++ and Fortran. It has
partial support for Go, Java, Obj-C and Obj-C++."
