It is almost always a mistake to set CFLAGS in make.conf.  Not only does 
it not improve performance, it frequently causes problems.  It will 
sometimes decrease performance for ports that can safely use custom 
CFLAGS themselves, because it prevents them from using those custom 
flags.

In other words, custom CFLAGS provide few or zero improvements, and have 
a significant risk of causing problems.
