[PATCH] dtors run twice on dll detach

I ran into a problem when is was trying to build STLPort-4.5.3 as dll (if
somebody is interested i can send him my patches). A program build with
this dll crashed in _free_r on termination. After testing a while i
discovered that the dtors were run twice, the first time from
dll_global_dtors, the second time from dll_list::detach which resulted in
a duplicated free for the same pointer.
Since i can not judge which function is obsolete (i guess dll_global_dtors
is) i have attached a small patch that will make sure that the dtors run
only once.

	* dll_init.h (per_process::dtors_run): New member.
	* dll_init.cc (per_module::run_dtors): Run dtors only once.
	(dll::init): Initialize dtors_run flag.
