It should be; I managed to use it to build on Debian etch on Wednesday...

It sounds like you effectively did a hacked-up variant of the ecj build.
The naming is perhaps a misnomer.  The ecj build is the default, and uses
your system jdk to build IcedTea.  A number of patches are included to
accomodate older versions of ecj, GNU Classpath/gcj etc.  It then uses this
build to bootstrap a clean IcedTea build as you just did.
--with-icedtea is a shortcut
option to skip to the second stage if you already have a copy of IcedTea new
enough.

If ${JDK_INSTALL} is the location of your installed JDK (be that
IcedTea, gcj-jdk
or whatever) the following options can  be used:

./configure --with-gcj-home=${JDK_INSTALL}
--with-libgcj-jar=${JDK_INSTALL}/jre/lib/rt.jar \
 --with-java=${JDK_INSTALL}/bin/java
--with-javah=${JDK_INSTALL}/bin/javah
--with-jar=${JDK_INSTALL}/bin/jar

You can fake this setup from a Classpath + VM install.

mkdir -p fake-jdk/bin
ln -s ${VM_INSTALL}/bin/${VM} fake-jdk/bin/java
ln -s ${CLASSPATH_INSTALL}/bin/gjar fake-jdk/bin/jar
ln -s ${CLASSPATH_INSTALL}/bin/gjavah fake-jdk/bin/javah
mkdir -p fake-jdk/jre/lib
ln -s ${CLASSPATH_INSTALL}/share/classpath/glibj.zip fake-jdk/jre/lib/rt.jar
mkdir -p fake-jdk/lib
ln -s ${CLASSPATH_INSTALL}/share/classpath/tools.zip fake-jdk/lib/tools.jar
mkdir -p fake-jdk/jre/lib/${ARCH}/{client,server}
ln -s ${VM_INSTALL}/lib/libjvm.so fake-jdk/jre/lib/${ARCH}/client
ln -s ${VM_INSTALL}/lib/libjvm.so fake-jdk/jre/lib/${ARCH}/server
ln -s ${CLASSPATH_INSTALL}/include fake-jdk
