Can you point us at a log? I'd like to see exactly where the confusion

Not sure why the set/unset situation is a problem. If OPENJDK is set
then it must be set to true else the sanity checks fail.
But we should locate anywhere that the make files still examine the
environment for such variables - not that I thought there were such
places. The environment variables should only be used to influence how
configure runs, and the variables it sets should then be used by the
