libdl: add option for controlling dl_cleanup
When debugging memory leaks with Valgrind, it is required that
dynamically loaded shared objects are not unloaded when a process exits,
otherwise symbols from those files aren't correctly resolved in
allocation traces. This patch adds the LDSO_NO_CLEANUP configuration
option to control this behaviour.
