Thanks for this tip! I didn't know, that it's possible to use environment 
variables for this. But the question remains: how to correctly use these 
settings in make.conf. Because even in the /usr/share/examples/etc/make.conf 
it's documented to use CFLAGS= (without the +). But doing it that way, these 
settings break port builds.
