Sorry the errors you see are unknown to me, I rarely run manual cross compiles, I prefer building on target.

The OpenEmbedded meta-java can automate a cross compile of JamVM + OpenJDK 6 or 7.

Build instructions:

I think meta-java can help you perform a cross compilation.

I build it on target like this: http://labb.zafena.se/?p=576

JamVM is pre-packaged for use on Debian/Rasbian and Ubuntu systems.
Simply install:
apt-get install openjdk-7-jre icedtea-7-jre-jamvm
and then run jamvm using:
java -jamvm
