[PATCH v2 0/3] Predictable ELF destructor ordering

[Florian Weimer <fweimer@redhat.com>]

These patches remove the dependency sorting from dlclose and process
shutdown, so that destructor order is the reverse of constructor order
in more cases (always if the process does not call dlclose).

Tested on i686-linux-gnu and x86_64-linux-gnu.  Built with
build-many-glibcs.py.

Thanks,
Florian

  elf: Do not rely on relocation dependencies for destructor sorting
  elf: Do not run constructors for proxy objects
  elf: Always call destructors in reverse constructor order
