Trent is right...  Except that now I can't even build AS root!!!

Please revert changeset 4d008d32fdcb.

A better idea would be to put this new functionality into a new command, 
like 'make build-system' and let it be optional.  This way, users that 
don't need this wont use it, and those that do need it will run only 
this command as root.

This also ensures that only the step that requires root access be run as 
root.  Im sure you would agree that the actual modules should not be 
built as root.  The only other thing that should require root access is, 
'make install'.

Right now, the only way that I can build is by doing this:

hg export 4d008d32fdcb | patch -R -p1

before make.  :-(
