I've seen the same thing, and what I was told when I asked is that it is
currently not possible with the version of GCC in -current to build from
ILP32 -> LP64. (Although I *know* I built a Sparc64 snapshot a while back on
-current, including the 64bit kernel.. so I don't know. I think that
something that used to work is now broken, but I'm no toolchain guru.)
