Ugh, do we have to have both mipsel and mipseb directories for this?
   
   I think we should use ${MACHINE_CPU} (==mips) for directory names.
   mipsel/mipseb should be used only to specify binary compatibility,
   not to specify source directories. Currently we are sharing all sources
   among both endians and never have had */arch/mipse[bl] dirs.
   (under lib/libc/arch, gnu/usr.bin/{egcs,gas.new}/arch etc.)


i didn't really agree with it, but this is how tv has the new toolchain
setup working.  this will be restricted to it.
