sorry about that: I don't test the 64-bit default configurations so far,
and didn't even have the necessary support libs around to do so. The
problem was that sparc/sol2-64.h was included too late and
DEFAULT_ARCH32_P was wrong for those configurations.
The following patch should fix this:
2011-06-27 Rainer Orth <r...@cebitec.uni-bielefeld.de>
* config.gcc (sparc*-*-solaris2*): Move sol2-bi.h after
sparc/sol2-64.h.

At least I can build the 64-bit libgcc now, but the 32-bit one fails for
unrelated reasons:
