The breakpoint could be added into the appropriate code in the dynamic linker
(i.e., the place calling the constructor for the object.  That code is already
relocated.

It is wrong to change the semantics of RT_CONSISTENT.  And I think it is a bad
approach trying to extend this strange interface with the debugger by adding a
RT_RUNNABLE state (I made up the name) for when the relocation happened, too. 
If we need more state information it is better to expose some APIs.  We have
libthread_db, maybe we need librtld_db as well.  If we'd have a specification of
what information of the implementation gdb currently contains and what it still
wants we can design such a library.

I guess I am waiting for gdb people to provide this information.
