 I assumed the trivial way to enforce it is to check the value of
 $WRKOBJDIR and emit an error/die if it starts with "/usr/obj/".

 I'd rather the case just be handled rather gracefully than let it go on
 with unexpected behavior.  If the decision is really that "/usr/obj/" is
 a sacred directory, then A) publish that in the pkgsrc guide and B) have
 pkgsrc enforce the limitation.  Obviously I'd rather there was no such
 limitation, but if that's not practical then so be it.
