[oe] [meta-java][PATCH 1/3] Don't depend on a hardcoded compiler

This patch creates a circular dependency for me:

ERROR: Unbuildable tasks were found.
These are usually caused by circular dependencies and any circular
dependency chains found will be printed below. Increase the debug
level to see a list of unbuildable tasks.

Identifying dependency loops (this may take a short while)...

I have set PREFERRED_PROVIDER_virtual/java-native = "jamvm-native" and
PREFERRED_PROVIDER_virtual/javac-native = "ecj-bootstrap-native"

The recipe ecj-bootstrap-native now depends on virtual/java-native and
provides virtual/javac-native.
The recipe jamvm depends on virtual/javac-native and provides
java-native. So none of them can be built since this patch.

Shouldn't jamvm depend on javac-initial-native?

Mit freundlichen Grüßen,
Sven Ebenfeld
