As Pieter pointed out, using CFLAGS+=... in /etc/make.conf
should work (i.e. ``+='' instead of ``='').  Did you try
that?

Just out of curiosity, I'm wondering why you want to set
the CFLAGS globally in /etc/rc.conf?  There aren't many
good reasons to do so, at least on i386 and amd64.  Most
of the time people change their CFLAGS they make things
worse.
