don't build/install manpages to nonexistent tools

[Ralf Wildenhues]

Hello there,

This allows to install a CVS version of coreutils on a host that does
not support all tools.  For a release tarball, this in itself wouldn't
be needed, as it ships them.  The second improvement however is that it
installs only the manpages for tools that are actually built.  Still,
it is ensured that 'make dist' can only work when you have all manpages.
A cosmetic downside is that they aren't built alphabetically any more.

Cheers,
Ralf

        * man/Makefile.am (dist_man_MANS): Replace all optional manpages
        with `$(MAN)', computed at configure time; also, list them ...
        (optional_mans): ... in this new variable.
        (max_aux, EXTRA_DIST): Ensure that we distribute all manpages.
