Also, now that gcc 3 seems to have better support for specific sparc 
processor optimization (e.g. supersparc, hypersparc), the SUN4M 
config can have examples in it like:

#makeoptions	CPUFLAGS="-mcpu=supersparc -mtune=supersparc"
#makeoptions	CPUFLAGS="-mcpu=hypersparc -mtune=hypersparc"	# Ross CPU
#makeoptions	CPUFLAGS="-mcpu=v8"		# {micro,turbo}SPARC

So that the generated kernels are not only sun4m MMU specific, they 
could also be better optimized for the particular processor a given 
user's system might have.

Given how old these systems are, I think we should offer all the 
assistance we can to the users so they can get all the performance 
these systems are able to deliver.
