>Description:
	When the CFLAGS are not altered by /etc/make.conf (such as
	by setting the CPUTYPE) or by local Makefile(s), the default
	value contains a blank space at the end: "-O2 -fno-strict-aliasing
	-pipe ".

	Not sure, whether this is a problem with the make code or with
	the /usr/share/mk/*, but I'm afraid, it is the former.

	It is known to be reproducible in 7.x as well as 6.2.

>How-To-Repeat:

	Run make with the following simple two-line makefile:

	echo:
		# >${CFLAGS}<

	Note the extra space before the closing ``<'':

	# >-O2 -fno-strict-aliasing -pipe <
