Darwin's linker defaults to requiring all symbols to be defined at
static link time (unless specifically noted or dynamic lookuo is
enabled).

For this test, we just need to note that the symbol is expected to
be undefined.

	PR testsuite/114036

gcc/testsuite/ChangeLog:

	* gcc.misc-tests/gcov-14.c: Allow for 'Foo' to be undefined
	on Darwin link lines.
