Yes, this is a real difference in command line option processing between
gcc and clang.  Probably for old-time compatibility's sake, gcc just
passes unknown options through to the linker, while clang seems to just
swallow them. :)

As a workaround, you can use "-Wl,-r", if that is possible for your
projects.
