[Ingo Schwarze]

Hi,

Werner's latest commit adding meintro_fr broke the build.
Here is the tiny fix.

Yours,
  Ingo

        * doc/Makefile.sub: Let the build access the preconv binary.

        This got broken in e66656a9b931cc4a253d7c454dc7550994a5431c
        when the -k flag was added to the groff invocation without
        adding preconv to $(groff_bin_dirs).
