Error found. I will send-pr. Patch below stored in :
http://berklix.com/~jhs/src/bsd/fixes/FreeBSD/src/gen/share/mk/sys.mk.REL=ALL.diff
pipe should not be on by default as
- It cripples machines with limited memory.
- Pipe can be enabled by any memory rich host in /etc/make.conf with:
CFLAGS += -pipe
- Man cc lists how to turn it on but not off.
- Man cc also notes assembler problems
