I messed round with fat binaries on Darwin a while ago so looking at
that this is all you should need:

CFLAGS+=  -arch x86_64
LDFLAGS+= -arch x86_64

For 2) I'm not sure but I have seen some posts of mk.conf magic in the
past where a setting was made to apply to one package but not all.  I'm
not sure how to do it myself but there should be something if you search
through the mail archives.
