You're looking in the wrong place.  If you want to build OpenJDK over
JamVM, go to http://icedtea.classpath.org.

To build IcedTea with JamVM:

hg clone http://icedtea.classpath.org/hg/icedtea6
./autogen.sh
./configure --disable-bootstrap --enable-jamvm
make

Come over to IRC channel #openjdk on irc.oftc.net for help.
