 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 `?='.
