[PATCH xrandr 2/3] Autotools: handle translated manpage #37612

[David Prévot]

This is a second part in order to fix #37612: partial patch against the
current build system to handle them.

Still need to be added to the building process:
- call the translated-man target in man/ (that could be done only inside
  a dist target, if you don't want to add an extra build dependency in
  po4a);
- appropriate cleanup and handling of copying translated manpages where
  they belong during the build process.

I'm not really confident with Autotools, so I've not proposed a patch
that works out of the box, sorry about that.

On the po4a side: if a new man/po4a/po/$lang.po is added, the
corresponding man/$lang/xrandr.man will be build by calling the
translated-man target in man/ (no need to edit anything in
man/po4a/po4a.cfg).
If an addenda (man/po4a/add_$lang/$lang.add) is provided, it will be
used (useful for translation credit), but it is not mandatory.

I used a build process like the one used in man-db: translated manpages
are handled in there own man/$lang/ directory. Since the manpage is
modified during the build process, it needs its own Makefile, so I added
it into the repository.

Some parts might be simplified (e.g. since the Makefile in man/$lang/ is
trivial, maybe could it be generated during the build process instead of
being stored in VCS, translated manpages could also be built directly in
the man/ directory).

I'm willing to provide more input on the po4a side, but would need a
better understanding or some help regarding the build process.
