Kernel and world seem to be ok with -O2, for ports it is not advised.
I have this in /etc/make.conf:

# -- all -- #
.if ${.CURDIR:M/usr/src*}
CFLAGS=-O2 -pipe
.else
CFLAGS=-O -pipe
.endif

CPUTYPE?=pentium3

# -- ports -- #
WITH_OPTIMIZED_CFLAGS=yes

So kernel and world (which source lives in /usr/src) are built with -O2,
while anything else is built with -O.  Some ports allow optimized
compiler flags with WITH_OPTIMIZED_CFLAGS.
