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

[Robert Menteer]

I have a Makefile created using the auto tools and it has a problem when making the ‘check’ target. The problem is the make file fails to verify the existence of runtest. The command used to test for the existence of runtest is:

if /bin/bash -c "runtest --version" > /dev/null 2>&1; then

What I found by running runtest by hand is it fails if the file site.ext exists. 

parallels@parallels-Parallels-Virtual-Platform:~/Desktop/Parallels Shared Folders/FlDist/trunk/testsuite$ runtest --version
