It's used to keep the object build by 'make world' or any of a number
of other makes ('make all', for example.

It's not much use if you plan to do a 'make world', since 'make world'
first goes and selectively removes all the directories it wants in
/usr/obj, and then recreates them.

I think that's reasonable. I have a recollection in the back of my
mind that other makes also use /usr/obj, and some of them don't know
how to make the directories if they're not there, but 'make world' has
no problem with it, and the makes in the Ports Collection don't use
it.
