bug#44580: DejaGnu runtest not found of site.exp exists

[Robert Menteer]

Jacob,

Thank you for the quick response. You did a beautiful analysis of what failed, 
not only determining what was wrong with the site.ext file but the input that 
caused another build tool to generate an incorrect file. I laughed out when I 
read your ending: this is not a bug but we’re fixing it anyway.
