Sebastian, Corinna,
This patch makes calls to expensive clean up functions as weak
reference, so one can still keep original functionality by explicitly
pull-in symbols. Comparing to simply skipping them to _exit or _Exit,
this approach is more flexible and testing friendly. In another word,
user can still get a full functional libc even if it is built with
--enable-lite-exit.
Please let me know if you still have concerns.
