description:
mk/compiler/gfortran: Default to same major version as base GCC

GFORTRAN_VERSION should match CC_VERSION as closely as possible for
ABI compatibility.  This update tries to match GFORTRAN_VERSION
to CC_VERSION if the base compiler is GCC.  If base compiler is not
GCC, default to a mainstream version likely to work with base clang/llvm.
