`info libtool "Tags"` describes them as a language that libtool supports
for the LT_LANG macro, alongside (in the version I'm using) C, C++,
Java, Fortran and Go. LT_LANG([Windows Resource]) does check for a
resource compiler named i686-w64-mingw32-windres or similar, and puts
it in the output variable RC; it's the intended steps after that that
are less clear.

The bug that I'm replying to (#25914) is a libtool enhancement request
asking for the way this is meant to work to be documented (including
whether it is meant to involve adding additional rules, and if so, what
those rules should typically be).

I am not a Windows developer (although I co-maintain dbus, which is
portable to Windows) so unfortunately I don't have a correct answer for
that, only anecdotal evidence based on what did and didn't work in dbus.
