Because `echo' and `install' aren't referenced in the default rules.  This
argument also applies to the following macros in sys.mk:

	unix
	.LIBS
	X11BASE
	AR, ARFLAGS, RANLIB
	CPP
	LDFLAGS
	LINT, LINTFLAGS
	RC
	MAKE
	SHELL

I don't think it has the equivalent of bsd.subdir.mk.  Printing the
current directory when make is started would be easy.  gmake prints
`Entering directory foo ... Leaving directory foo'.  It is noisy.
