Well, you need to know that the library got loaded so you can decide
whether you want to set a breakpoint there before it gets a chance to
execute. It's the same thing as the dynamic linker rendezvous
breakpoint, only for jitted code.

**I suppose** delay the lookup until the first breakpoint gets set by
the user, as that is the first time we will need that information, but
I guess we don't have the ability to express that now.


FWIW, the jit interface can be disabled by a setting
(plugin.jit-loader.gdb.enable-jit-breakpoint).
