Oy, I can't believe I overlooked that file.  I've updated the patch
(see below).

> and add powerpc detection in cmd/mkfile.

I added a detection to not make dtracy on powerpc and everything else
under /sys/src/cmd built.  It's included in the patch below.  I'm
testing that all the "supported" archs build.  Even tho' ppc cmd now
builds, the two powerpc kernels (mtx and ppc) still fail for different
reasons.  This is the rc script I use:

#!/bin/rc
echo Updating system
sysupdate || exit 'sysupdate failed'
. /sys/lib/rootstub
cd /sys/src
objtypes_default=`{cat mkfile.proto| grep 'CPUS=' | sed -e 's/CPUS=//'}
if (~ $objtypes '')
	objtypes=($cputype `{{for (f in $cputype $objtypes_default) echo $f} | sort | uniq -u})
for (objtype in $objtypes)
	for (mk in nuke all install clean)
		mk $mk || exit 'mk '^$mk^' failed for '^$objtype

cd /sys/man
mk || exit '/sys/man failed'

cd /sys/doc
mk || exit '/sys/doc failed'

cd /sys/src
mk kernels || exit 'mk kernels failed'

Thanks for the link.  I remember you working on this, but didn't
follow it closely.
