Jon, please apply.

I don't think this fix is perfect - for example, I wonder what will
happen if /bin/echo is actually a busybox instance.  But it's
definitely better than right now, where the testsuite will give
failures out of the box on the default setup for several major
distros.

And as Stephen suggests, I would prefer not to make the test scripts
bash specific.
