Since a very long time ago I have this in my /etc/mk.conf:

.if ! ${CFLAGS:M-pipe}
CFLAGS += -pipe
.endif

My machine has loads of memory but no local disk - so this speeds
up compiles quite a bit. When doing make in, say, /usr/src/bin/ls
everything is fine. When compiling a kernel, no -pipe is used.

I don't know if this ever worked, is it supposed to?
