V3 PATCH: mkcheck.in vs Bash 2

[Mark Mitchell]

The mkcheck.in script apparently requires GNU Bash version 2.  It
checks for this, and exits immediately if the right version is not
available.

Unfortunately, since this script is also used as part of `make
check-g++', this means that you can't run the C++ tests on a machine
without Bash 2.

We'd have to rewrite this script in plain portable shell, except that
Gaby is converting the V3 testsuite to DejaGNU anyhow.  But, in the
very short term, this patch just makes it possible to run the C++
testsuite -- as long as you have some version of Bash installed.
