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. Signed-off-by: Richard Braun <rbraun@sceen.net> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

+ If you need complete allocation traces when debugging memory leaks
