It does the same thing as OPT_static_libgfortran and that option
presumably isn't disabled on Darwin.
My guess is that this is just dead code and could be removed for both
options, I think gfc_handle_option is only in f951 program, and the
-static-lib* options are driver only, not passed to the compiler.
Note, for other options like -static-libstdc++, we also don't reject them
if HAVE_LD_STATIC_DYNAMIC isn't defined.
