Latest CVS: small portability issues

[Lutz Jaenicke]

Hi!

I just run a test build of the latest CVS on HP-UX 10.20 and found two 
issues, both related to the new mdoc2man.pl support:
- In Makefile.in, line 122, the construction
  $(MANPAGES): %.out: %
  is used. HP's "make" command does not understand this syntax (gmake does).
- In configure, the first "perl" command in the PATH seems to be found.
  On HP-UX this is an ancient Perl-4, that cannot handle mdoc2man.pl.
  I would recommend to try to detect a "perl5" in PATH first and only then
  fall back to "perl" in the PATH.

Best regards,
	Lutz
