CPYTYPE is make.conf and -march in gcc are different things.
After a lot of reading (/usr/share/examples/etc/make.conf and man gcc)
and testing, here is what I use for my core2 :
CPUTYPE=core2
CFLAGS=-O2 -pipe -march=native
NO_CPU_CFLAGS=yes
COPTFLAGS=-O2 -pipe -march=native
NO_CPU_COPTFLAGS=yes

I think you can use the same for your i5.
