FortranCInterface: Make mangling detection robust to PIC Fortran
When using a Fortran compiler that produces PIC executables by default
with a C compiler that does not produce PIC by default then the mangling
detection executable fails to link. Explicitly enable PIC for the C
compiler just in case the Fortran compiler needs it to link.
Issue: #16405
