>Description:
	Make will re-make libraries in the source tree unnecessarily.
	This type of behaviour is also observed when building some third
	party source (binutils-2.8.1 comes to mind).  With binutils,
	gmake does things "properly".

>How-To-Repeat:
	Type the following:

		% cd /usr/src/usr.sbin/ypserv/common
		% make
		% make
		% make

	and observe:

		vlad:~ 54> cd /usr/src/usr.sbin/ypserv/common
		vlad:usr.sbin/ypserv/common 55> make
		cc -O -fPIC -DPIC -DABICALLS -Werror -Wall -Wstrict-prototypes \
			-Wmissing-prototypes -Wpointer-arith \
			-I/usr/src/usr.sbin/ypserv/common/../common \
			-I/usr/src/usr.sbin/ypserv/common/../common -c \
			/usr/src/usr.sbin/ypserv/common/localhostname.c
