x-to-1: Honor $PERL

Browse source 
* tools/x-to-1.in: Run $HELP2MAN via $PERL so that the user gets a
chance to use his preferred version of Perl.  This is typically
required by Darwin users whose default /usr/bin/perl do not have all
the libraries required by help2man, and who need to use their MacPorts
installation of Perl instead.
