You can't run make from a obj directory there is no Makefile, Targets or 
spoons. ;)

This line here:
BW_CANONICALOBJDIR:=${MAKEOBJDIRPREFIX}${.CURDIR}

Allows the end-user to set MAKEOBJDIRPREFIX in their environment and have 
the obj directory somewhere other than CANONICALOBJDIR.

BW is an abbreviation for "buildworld".
