I never managed to get that to work.  I think what probably shoul be done 
is rather than use /emul/netbsd32/usr/bin/gcc, get /usr/bin/gcc to DTRT 
when given the -m32 flag to bring in the correct header files and link
against libraries in /emul/netbsd32/...

What I ended up having to do to compile 32 bit systems was to have a
full 32-bit SPARC partition for /emul an boot that with a 32-bit kernel.
