And it's overrided, always. sys.mk defines CPP and bsd.port.mk exports[1]
it to descendant make(1) or gmake(1).
[1] since ports/151047 was committed a few months ago there were a few
fallouts that required `CPP = ${CC} -E' or `CPP = # empty', e.g.
chinese/cless (empty)
games/angband (cc -E)
games/xtux (${CC} -E)
graphics/xpx (empty)
sysutils/logrotate (${CC} -E)
irc/dancer (empty)
japanese/ircII (empty)

And? I use symlinks/PATH, e.g. cc -> ccache -> gcc45.
But both ways don't help for above ports.

Try setting it from environment or make.conf. Assignments on command
line override even `=', not only `?='.
