And I doubt you do a build with a stock /etc/src.conf on such hardware either.
The defaults for src.conf should be for the common case, and in the common 
case profiled library builds are in the noise.  I do add WITHOUT_PROFILE to 
many of my machines in /etc/src.conf, but I still think they should be enabled 
by default.
