Updating to an unreleased gcj is certainly not necessary.  We do regular builds
with 4.5 and 4.6 and there are no issues.  Please ignore Xerxes' comment.

I don't see any obvious problems with your configure options (though export
ALT_PARALLEL_COMPILE_JOBS="${MAKEFLAGS/-j}";  export
HOTSPOT_BUILD_JOBS="${ALT_PARALLEL_COMPILE_JOBS}" should be replaced by passing
--with-parallel-jobs=${MAKEFLAGS/-j} to configure).

I do see a problem with your gcj build environment:

ln -sf /usr/bin/gcj ${_gcjjvm}/bin/javac

gcj is not a replacement for javac; it's a source to native code compiler, not
a source to bytecode compiler.  That's why this test will be failing; you can
check config.log for the details.

The following can be used instead:

echo "Creating javac script"
echo "#!/bin/bash" > ${JDK_DIR}/bin/javac
echo "${VM_BINARY} -classpath ${ECJ_JAR} \
org.eclipse.jdt.internal.compiler.batch.Main \"\$@\"" \
    >> ${JDK_DIR}/bin/javac
chmod +x ${JDK_DIR}/bin/javac

which will run ecj.
