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

[G. Branden Robinson]

Follow-up Comment #61, bug #63808 (project groff):

[comment #58 comment #58:]
> A message from configure the URW fonts are not found.
> No warnings from BuildFoundries.
> Only the default foundry groff fonts (base-35 plus EURO).
> check-default-foundry has passed.
> check-urw-foundry is not run/skipped.
> All pdf docs produced with no unexpected warnings.
> 
> If all the above then it is a successful run, 

What this means is that comment #54 doesn't look so good after all.

>From my re-contrived build, with urw-base35 installed but moved aside, and
Ghostscript's Resource/Font also moved aside, but replaced with your font
archive from comment #41, I have the following.

configure: Buggy version of Ghostscript detected.

  Ghostscript versions 9.00 <= x < 9.54 suffer from a rendering glitch
  that affects the AT&T troff (and groff) special character '\(lh'; see
  <https://bugs.ghostscript.com/show_bug.cgi?id=703187>.  If your
  version of Ghostscript has not been patched to fix this problem, you
  may need to work around it in groff documents you render for the
  PostScript (and, for tbl(1) tables, HTML) output devices.
  
configure: The uchardet library was not found.

  The 'preconv' preprocessor program will be unable to attempt automatic
  inference of an input file's character encoding.  See the preconv(1)
  man page.
  
configure: The program 'psselect' was not found in $PATH.

  Consequently, groff's HTML output driver, 'grohtml', will not work
  properly.  It will not be possible to prepare or install
  groff-generated documentation in HTML format.

Success, but only because BuildFoundries bombed when it tried to generate the
URW font descriptions, which it should not have tried to do.

Didn't get that far.

Didn't get that far.

Didn't get that far.

So what I will do is drop the "gs -h" scraping from our Autoconf macro
GROFF_URW_FONTS_CHECK, and see what happens then.
