[patch] Add missing observer_notify call.

[ppluzhnikov@google.com (Paul Pluzhnikov)]

Greetings,

In http://sourceware.org/ml/gdb-patches/2009-07/msg00553.html
Pedro noticed that a new objfile may be created without notifying new_objfile
observer.

Here is a fix. Tested on Linux/x86_64 with no new failures.

Thanks,
