The instructions I gave are for GNU Classpath and an appropriate VM, not gcj.

gcj already has build options to mimic a JDK setup:

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

where GCC_INSTALL is the prefix you're installing gcj too.

Alternatively, symlink the binaries:

Rather than just running the IcedTea build, it would be sensible to make sure
all these binaries work beforehand; primarily javac, javah, java, jar, rmic and
javap.  IcedTea has options to override the default locations of all these. 
See ./configure --help.
