This chunk probably needs a bit of explanation: since I need to
substitute the location of the installed man pages into the avr-man
script, I needed an autoconf macro for them.  While `make' could cope
with both forms of parenthesation, shells scripts need the ${...}
form.  ($(...) substitutes stdout from an external command in the
shell.)
