Using GNU GCC as a cross compiler

[esunix!sim.dnet!kpoppleton at cs.utah.edu]

Can the Gnu GCC compiler be used as a cross compiler.  We need a good
compiler to create 68000, 68010, 68020 and 68030 code which runs on a Sun
4 machine (SPARC).  The GNU compiler has been recomended as a good
compiler and I would like to also use it as a corss compiler.  If it can
be set up to create Sun 3 code while running on a Sun 4, then it would do
the job.

Thanks in advance for any information.
