Some subtargets don't provide the canonical function names as
the symbol name in C libraries, and libcalls will only work if
the builtins are patched to emit the correct library name.
For example, on NetBSD, cabsl has the symbol name __c99_cabsl,
and the patching is done via netbsd_patch_builtin.
With this change, libgfortran.so is correctly built with a
reference to __c99_cabsl, instead of "cabsl" which is not defined.
