[avr-libc-dev] cxa_aexit issue

[Joerg Wunsch]

We've got some workarounds, but I hope someone can help use find the
real issue and possibly also solve it. You may have a look at it more
https://bugs.archlinux.org/task/50848

After looking at it, it's not quite sure what we are supposed to do
here.

If we can supply some kind of _cxa_exit(), that's certainly an option
(assuming someone can tell me what to do there ;-).
