this is wrong: for one, it needs to allow for 64-bit-default SPARC
configurations (i.e. sparcv9-*-* and sparc64-*-*), and AFAICS there's
nothing Solaris-specific here. So this should be sparc*-*-* instead.

Fine with me. If the list gets much longer or the conditions more
complex, it might still be worthwhile to use an effective-target keyword
instead.
