Because ant expects a Sun JDK layout...

GCJ 4.4 has an option to generate this layout:

--with-java-home=$GCC_INSTALL --enable-java-home \
    --with-jvm-root-dir=$GCC_INSTALL/jdk

It seems something is broken with regard to Ant.  The fact it's
looking for tools.jar in your gcj home directory rather than
bootstrap/jdk1.6.0 suggests it's ignoring the setting of
bootstrap.java.home.  Have you checked that bootstrap/jd1.6.0 has a
valid jar file in jre/lib/rt.jar?  I would guess it does as the
earlier stages have worked, but Ant is reverting to your system
install.
