I wonder if we could ignore the environment altogether with:

env -i PATH=$PATH make

The output of env/set after this is only PATH and anything make/bash export. 
This should provide isolation from anything in the users normal env without 
having to stumble across them and manually unexport them. We could add this to 
the docs or modify the recursive "make build-only-foo" call.

Any thoughts?

Cheers,
