	Which will really annoy those running on older lower memory

	Maybe we could have /usr/share/mk/... check for CFLAGS_PIPE, and
	if not set use 'sysctl hw.usermem' to set it based on the amount
	of user memory. This would them be pushed into the enviromnent so
	any nested make processed would not have to check again.

	Obviously you can set CFLAGS_PIPE to YES or NO to override this.

	What would be the correct amount of memory - 64MB?
