I'm just waiting it done for a month.

Currently, any {mipsel,mipseb,m68k,powerpc,sh3el} binary run on
any {mipsel,mipseb,m68k,powerpc,sh3el} archtecture.
So that is not a reason to introduce "a new technique."

I meant these changes:
- usr/include/machines points to include/arm, not include/${MACHINE}
- creating /usr/include/arm/${MACHINE} directories
- arch/arm/conf/Makefile.arm creats ${COMPILEDIR}/include/${MACHINE}
  and ${COMPILEDIR}/include/machine directories

I think any chaneg of framework like this should be done
among the all archtecture.

For NBPG, sun4 and sun4[cm] machines have different NPBG,
but they are in a common port.
