[Bug libgcj/33278] New: [4.3 Regression] libjava fails to compile if configure argument contains "version"

[belyshev at depni dot sinp dot msu dot ru]

When gcc is configured with, for example, "--without-pkgversion", this part of
libjava configure script parses "gcj -v" output incorrectly, thus encoding
garbage as preprocessor macro and failing:

gcjversion=`$GCJ -v 2>&1 | sed -n 's/^.*version \([[^ ]]*\).*$/\1/p'`

An obvious fix would be:

        * configure.ac: Encode the libgcj soversion in dbexecdir,
        pass --with-native-libdir to classpath configure.
        * configure: Regenerate.
