Workaround for configure script and old `test' commands which do not support

the -x flag (for instance under platforms like Ultrix). This is solved by
another helper script findprg.sh which searches for Perl and Awk like
PrintPath but _via different names_ (BTW, no I don't wanted to change/enhance
PrintPath because we also have PrintPathOS2 etc.  and if we merge the stuff we
have to touch a lot of things. When we want to reduce things later we can use
findprg.sh instead of PrintPath, but we have to be carefully).
