FYI, to my knowledge no one has ever used CMake with that compiler.
We need to teach CMake about the compiler's flags.

Is the compiler derived from a GNU compiler?  Somehow its preprocessor
claims that the compiler is GNU.  Do you know if the compiler documents
a preprocessor symbol to identify it?

The workaround is:

set(CMAKE_SHARED_LIBRARY_LINK_Fortran_FLAGS "")
#                        ^^^^

I don't think that has anything to do with it.
