* Makefile.am: (write_entries_to_file) New parameterized

	function for writing entries to a file one line at a time.
	(all_java_class_files): Removed definition.
	(.java.class) Removed.target.
	(libgcj-@gcc_version@.jar): Changed dependency to
	$(all_java_source_files); added compilation step which compiles
	all changed source files in one pass.
	(libgcj.la) Refactored to use write_entries_to_file.
	(lib-gnu-awt-xlib.la) Likewise.
	(install-data-local) Likewise.
	(write-entries-to-file-check) New target which tests write_entries_to_file.
	(all-recursive): Changed dependency from $(all_java_class_files)
	to libgcj-@gcc_version@.jar
	* Makefile.in: Rebuilt.
