libgcj-$VERSION changes

[David S. Miller]

Anthony, why did you hard code the value for the version
number in the 3.1 branch version of your libjava.exp change:

2002-04-11  Anthony Green  <green@redhat.com>

        * lib/libjava.exp: Use libgcj-3.1.jar, not libgcj.jar.

Whereas on the mainline you used gcc_version which is really
how the libgcj-$VER number is determined by the build process?

        * lib/libjava.exp: Use libgcj-VERSION.jar, not libgcj.jar.

This is causing problems on the 3.1 branch now because gcc_version
is 3.1.1 but the testsuite is looking for libgcj-3.1.jar

So the whole libjava testsuite fails now because the classpath
is being set incorrectly.

It seems to me that your mainline version of the change should be put
into the 3.1 branch libjava.exp like so:
