I can, but the reason I added support to begin with is that we don't
use the system's bc-compiled ecj:

        ln -sf ../../../javac bootstrap/ecj/bin/javac

Instead, javac.in is used.  The overhead of rebuilding a ecj is not
ideal, agreed, but it's noticeably faster once
built than running the entire bootstrap stage with gij.
