Looking at src.conf(5), this is already default setting for amd64.  And 
given that it's default, no, I'm not seeing this doing buildworld with 
recent checkouts.

These settings don't do what you likely expect them to do as src.conf(5) 
explicitly states (and confirmed by your build log excerpt above):

      The values of variables are ignored regardless of their setting;
      even if they would be set to “FALSE” or “NO”.

So you'd want the WITHOUT ones.
