I firmly believe that /usr/include/machine should point to 
<arch> (e.g. mips) instead of <port> (e.g. pmax).  If you are
building specific programs to a port, then you should use
something <pmax/foo.h>.

This would go a long way to have a common userland per arch.

Things like disklabel.h need to special cased (I'd probably
use an array with port/labelsector/labeloffset) that disklabel
could search for the right value.
