Sorry about not responding to this thread earlier.  I was out for the
day, and will be out till late Sunday.

Yes, this code was heavily tested both with and without fpu.  Uli said
he had changed a few things related to exporting of symbols, perhaps
this is the cause of the problems, not sure.

The soft infrastructure should only be pulled in with --target of
powerpc-unknown-linux-gnusoft, which will also pass --without-fp

The __addsf*, etc routines need to be exported because gcc emits calls
to those.  If they're hidden, you'll get link failures.

I'll update my copies late this weekend and try to address any
problems resulting from this.  Sorry I can't do it earlier; I need to
pick up friends from the airport for the weekend...
