When compiling native MirOS BSD binaries with SUNpro 12 (don't look like a

car only slower, yes this is possible, and the resulting binary passes the
testsuite just fine), the definition of __RCSID() in <sys/cdefs.h> expands
to something with __attribute__((used)), which triggers a warning, because
__attribute__ in general is supported but the used attribute isn't. Thusly
always use our own strings and get rid of the MULTI_RCSID test (introduced
because __RCSID() on Darwin is inferiour).

Maybe we should fix <sys/cdefs.h> too? #ifdef __SUNPRO_C helps here.
