Prior to this patch, the Makefile.am needs to be modified multiple
places to add a new man or HTML page to be generated.  Since it is not
too often we modify this, it is easy to miss these finer details.

This changes the man and HTML generator rules to be more generic and use
variables as many places as possible.  Also moved all the lines which
should not need to be changed as much towards the bottom-half of the
file.

Tested on:
  - Linux, with docutils, including "make distcheck" + tarball check
  - FreeBSD 12, with no docutils, "make" succeeds, "distcheck" fails (ok)
  - FreeBSD 13, with docutils, including "make distcheck"

Your patch has been applied to the master and release/2.5 branch 
(no code change, eases our future maintenance).

commit 37cf98fa224a2ae5fc5cfa380bdb291e90d6413d (master)
commit 18211f1ba3124bde05ca11c5111989acdb27f957 (release/2.5)
