Fedora 8 is very outdated (3 years old). Although IcedTea (7) has been
bootstrapped on it, it isn't maintained anymore. You might have better
luck if you update to a more modern version (Fedora 14 is the latest).

IcedTea is a fully free Java Runtime and Development Environment. Build
upon OpenJDK extended with developer, user and web browser tools like an
Applet viewer, Java Webstart (LiveConnect and JNLP) support and
VisualVM, a lightweight profiler and troubleshooting tool. Bootstraps
with and provides alternative runtimes, tools and class library support
for Java and Java-like environments, like the Zero interpreter, Shark
JIT, GCJ native compiler, GNU Classpath core libraries and Cacao. See
http://icedtea.classpath.org/

OpenJDK is a free reference implementation for the Java Standard Edition
Developer Kit. Includes an execution environment, development tools and
a class library for the Java programming language. IcedTea extends this.

Yes, it should natively build on an arm board. But that might be slow,
so you might want to cross-compile...

See http://icedtea.classpath.org/wiki/CrossCompileFaq
