I hate it too, but I think the PATH setting for root might
have its roots in security (it's not clear from CVS history).
For example, as a user, I have "." in my PATH, but I would
prefer NOT to have it while I'm su'ing to root.

Until we decide how to properly do it, I think unbreaking
"buildenv" for the standard case would be polite.
