Enhance the relocation-based dependency (add_dependency) in _dl_lookup_symbol_x
to create a dependency on libc.so.6 and force it to be initialized first?

If *something* needs libc.so.6, then you should be able to use the relocation
dependency on the symbol to create the right initialization order.

If *nothing* depends on libc.so.6, then you don't have enough information to do
the appropriate action.
