This is the problem we are trying to "solve":

kim 1 % cd /usr/src
kim 2 % make targets
Supported TARGET/TARGET_ARCH pairs for world and kernel targets
    amd64/amd64
    arm/arm
    arm/armeb
    i386/i386
    ia64/ia64
    mips/mipsel
    mips/mipseb
    mips/mips64el
    mips/mips64eb
    mips/mipsn32eb
    pc98/i386
    powerpc/powerpc
    powerpc/powerpc64
    sparc64/sparc64
kim 3 %=20

We currently only do formal builds for a sub-set.  But as time goes
on who knows...  We could, for now, settle on just either `uname -m`
or `uname -p` so we only have one "name".  But note that's only possible
for 9.0 because pc98 builds aren't being done.  If we choose a scheme
that doesn't cause a conflict between the two powerpc builds we're doing
for 9.0 (powerpc and powerpc64) then if pc98 ever comes back we will
have a conflict between i386 and pc98.
