Weaken build dependency on TeX.
[build]: Weaken dependency on TeX, instead using it (to generate the DVI
and PDF forms of our Texinfo manual) only if it is available.
* m4/groff.m4 (GROFF_USE_TEX_CHECK): Check for presence of 'tex'
executable in path. Set shell variable `groff_use_tex` to "yes" if
present, and "no" otherwise. This check runs only if the 'makeinfo'
and 'texi2dvi' version checks have already passed.
* configure.ac: Run the new check. Set Automake conditional `USE_TEX`
only if shell variable `groff_use_tex` is "yes". Report whether
"groff.dvi" and "groff.pdf" are (re-)buildable.
* doc/doc.am: Parameterize names of groff.{dvi,pdf} targets as Make
macros `GROFF_DVI` and `GROFF_PDF`. Define them only if `USE_TEX`.
Do _not_ update `EXTRA_DIST` macro; leave the literal file names there
because we require that distribution archives contain these files.
(.texi.dvi, .texi.pdf): Update suffix rules to check `USE_TEX` and
fail, complaining of missing 'tex' program, if these targets are
attempted without it being true. Only manually specifying the file
names as targets to 'make' or attempting to generate a distribution
archive without TeX present should cause these errors.
* INSTALL.REPO: Update dependency information.
Fixes <https://savannah.gnu.org/bugs/?62592>. Thanks to Deri James for
the report.
