Well, if ccache was clever enough to support kernel builds then it would 
be ok. But since I've never managed to get it to work reliably I use:

.if ${.CURDIR:M/usr/src*} || ${.CURDIR:M/usr/obj*}
CC=cc
CXX=c++
.else
.if defined(NOCCACHE)
CC=/usr/bin/cc
CXX=/usr/bin/c++
.else
CC=cc
CXX=c++
.endif
.endif

Not sure if it is ccache itself or the make.conf example that is wrong.
