In general, that's not a good idea, IMO.

It should be up to the user to decide which optimizations
he wants and which not, and we do have /etc/make.conf and
CFLAGS for exactly that purpose.

I always hate super-clever makefiles and configure scripts
that strip -O from my CFLAGS and insert -O6 -march=i686 or
other unwanted things.  It's a PITA.

Just my 0.02 Euro.
