[bug #63808] configure gives incorrect information regarding pdf generation

[G. Branden Robinson]

Follow-up Comment #63, bug #63808 (project groff):

I think a see a way now to produce gropdf tests that can be skipped depending
on parameters determined at configuration time.

We can use the _existing_ AC_SUBSTed "$GHOSTSCRIPT" and "$urwfontsdir" shell
variables to generate the two test scripts from .in files with the usual
sed-based @REPLACEMENT@ trick, and perform tests upon these variables.

So check-default-foundry.sh would do something like this:


if [ "$GHOSTSCRIPT" = no ] || [ "$GHOSTSCRIPT" = missing ]
then
  exit 77
fi


...and check-urw-foundry.sh something like this:


if [ -z "$urwfontsdir" ]
then
  exit 77
fi


I'll throw in messages about why skipping is happening, of course.
