- * The old way of doing this is to define a macro 'target_new_objfile'

- that you want to be called on every objfile/shlib load.

- save a pointer to the previous value of
- deprecated_target_new_objfile_hook before modifying it, and arrange
- for their function to call the previous function in the chain. In
- that way, multiple clients can receive this notification (something
