Why would that be a problem?  libgcj.so the linker sees (i.e. the dummy
library) doesn't intentionally have DT_NEEDED libgcj.so.N, programs and
shared libraries linked with -findirect-dispatch should be adding
libgcj_bc.so to DT_NEEDED, not libgcj.so.N.

If this is caused by some recent broken linker change, then that should be
better reverted.
