Comment #33 on issue 1852 by address@hidden: manuals needs more  
explicit dependencies

Build dependencies for .texi files (issue 1852).

Write .dep files containing make dependency rules for .texi files.
These .dep files are generated by scanning for lines starting with
@include in the .texi files. They are included into the build by
the file stepmake/stepmake/generic-targets.make.

With proper dependencies it became apparent that the build system
does not operate correclty as make would then complain:

*** No rule to make target `weblinks.itexi', needed by `out-www/web.texi'.   
Stop.

This was triggered when we added the above dependency rules, and
shows that the build system now attempts to build weblinks.itexi
before compiling web.texi, but fails to do so because a rule is
missing. Thus we add the missing rule to generate weblinks.texi
to the local GNUmakefile in the Documentation folder.

Another issue are @include for which the included files are in
another directory, but that is not reflected in the @include.
This produces wrong dependency targets since make would expect
the included file in the same directory as the main file. Thus
we se @include with the correct relative path in .texi files.
