This is very obscure, but documented (I don't remember where, but I
found it when I was rewriting the make manual page at Tektronix).

The idea is that the "default target" is the first target in the file
that does not begin with a '.'. This is done so that you can do
things like

	.SUFFIXES: .c .s ...
	...
	all: $(PGM)
	...

and be able to say 'make' and mean 'make all'.

The easiest solution is to add the line

	all: .hushlogin

at the end of the file, so you end up with:

	.hushlogin:	/etc/motd
		@-cat /etc/motd
		@-touch .hushlogin

	all: .hushlogin

(The '@-' tells make to ignore exit codes and to not print the
data.)

Still, all this is no better than

	find /etc/motd -newer .hushlogin -exec cat '{}' \;
	touch .hushlogin

If you really want to see /etc/motd when it changes, use the "cmp"
stuff.
