be easy to change to /usr/X11R6 if and when the time comes. This is
to deal with things like xditview which otherwise had hardcoded assumptions
about where X lived. Yuck.

Add macros ECHO and ECHODIR. Both are normally `echo', but when
the make flags include -s, ECHO is set to `true' and when the make
flags include two or more -s's ECHODIR is set to `true'. @${ECHO}
should be used instead of @echo in most cases. ${ECHODIR} is
intended to be used mainly for messages about directory names.
