I'm also running it on raspberry, so I clone toolchain from here: 
https://github.com/raspberrypi/tools
Run this configure line:
CC=/home/geckos/raspberry-tools/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin/arm-bcm2708hardfp-linux-gnueabi-gcc 
JAVA_HOME=/home/geckos/java6/ ./configure 
--host=arm-bcm2708hardfp-linux-gnueabi --enable-java --enable-debug 
--disable-python --disable-notify_desktop --disable-perl 
--with-fp-layout=nothing

Cheers,
