Yay it works,

I have to explode the arm JRE inside x86 JDK/jre/, and set JAVA_HOME
So I have this two directories
JAVA_HOME/jre/lib/amd64
JAVA_HOME/jre/lib/arm

Here is the line I used.

CC=/opt/arm-2009q1/bin/arm-none-linux-gnueabi-gcc 
JAVA_HOME=/home/geckos/java6 ./configure --host=arm-none-linux-gnueabi 
--with-fp-layout=nothing --enable-java --enable-debug --disable-python 
--disable-notify_desktop --disable-perl

I'm using Sourcery CodeBench Lite Edition toolchain, if anyone cares..

Cheers!
