Log message:

        * powerpc/l4/bits/syscall.h (_L4_EXTERN_STUBS): Define macro and
        include <l4/bits/stubs.h>.  Then undefine it.
        * powerpc/l4/bits/stubs.h: Only error if _L4_EXTERN_STUBS is not
        defined.
        (_L4_EXTERN): New macro.
        (__l4_syscall_stub_t): Define as macro and only add typedef if it
        is not defined yet.
        Use _L4_EXTERN to prefix all system stubs declarations.
