This would be taken care of by the default settings of MACHINE_CPU=3Dev4, which would (if we went down this path, see my previous mail) add an explicit -mcpu=3Dev4 to the release (and all other) builds. If you know your builds are only ever going to be used on an ev5 or whatever, you can set MACHINE_CPU=3Dev5 ev4 in /etc/make.conf and the hypothetical makefile logic would use -mcpu=3Dev5 instead.
