Test if a Java class is available. Based on AX_PROG_JAVAC_WORKS. This version uses a cache variable which is both compiler, options and classpath dependent (so if you switch from javac to gcj it correctly notices and redoes the test).

The macro tries to compile a minimal program importing <class>. Some newer compilers moan about the failure to use this but fail or produce a class file anyway. All moaning is sunk to /dev/null since I only wanted to know if the class could be imported. This is a recommended followup to AX_CHECK_JAVA_PLUGIN with classpath appropriately adjusted.
