I could not find it in either man 0 mk.conf or man 5 mk.conf nor on the
Documentation website or /usr/pkgsrc/mk/defaults/mk.conf 
Sorry but I would not call your referance - documentation.
Anyway, I could not find any explenation of how to use the CPUFLAGS in
either
src/share/mk/bsd.README
src/share/mk/bsd.sys.mk
or src/sys/conf/Makefile.kern.inc

I assume it should be something like: CPUFLAGS=pentium4
Is that correct?
Thanks for the hint Lubomir.

Cheers,
Marcin.
