This will also help our 'SNGL' brand of SmartOS where we relocate the
core OS to /system and install pkgsrc into /usr - see my pkgsrcCon
2013 slides for more information.

What I'd like to see in addition to this is generalised handling for
mk/*.builtin.mk, which is something you will likely run into anyway.
Currently these files are not LOCALBASE=/usr clean, and abstracting
them away in a similar manner would be a great help.

I'd like to try this patch out in a bulk build at some point
(unfortunately not earlier than a couple of weeks from now), but in
principle I'm all for it.

Thanks,
