I just tried the latest glibc packages.  Works on the Ultra5 and SS20
with 2.2.5cvs kernel.  Doesn't work with the slink 2.2.1 kernel on the
SS20 (init wedges).  

I wonder if the sparc32 vfork patch is in the 2.2.6 kernel.

If I'm not mistaken, we'd essentially need a cross compiler named
sparc64-linux-gcc.  So, when the egcs package can handle compiling the
kernel, we'd have to tell it to build a cross compiler for sparc64
binaries (much like the cross compiler for m68k works).

--with-cpu=ultrasparc just does UltraSparc optimizations (code
ordering, etc) - we need to produce code for 64-bit mode (so some of
the type sizes are different - and some instrs are different) and
dump them into ELF64 object files.

Oh, I didn't know anybody noticed.  I'll work on it remotely when I
get home.  (If TCI isn't down.)
