[LIB]: Detect typedef loops 

Recheck if the typedef was emitted as part of the emission of its target, as
there are cases, like wait_queue_t in the Linux kernel, that is against struct
__wait_queue, that has a wait_queue_func_t member, a function typedef that has
as one of its parameters a... wait_queue_t, that will thus be emitted before
the function typedef, making a no go to redefine the typedef after struct
__wait_queue.
