What is the output of "cf77 --version"?

That may be what it tells cf77 but that is not what it tells
gcc.  From "man gcc":

 -rdynamic
     Pass the flag -export-dynamic to the ELF linker, on targets that
     support it. This instructs the linker to add all symbols, not only
     used ones, to the dynamic symbol table. This option is needed for
     some uses of "dlopen" or to allow obtaining backtraces from within
     a program.

Anyway we should drop it for cf77 once we can identify that compiler
as distinct from a GNU compiler.
