cxa_aexit issue

NicoHood
Hey guys,
we are currently facing an avr-gcc/avr-libc problem in Archlinux. With
avr-gcc 6.x we got the problem that cxa_aexit seems to cause issues with
lto if its disabled. We cannot enable it, as its not defined in avr-libc.

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
detailed here:
https://bugs.archlinux.org/task/50848

Cheers,
Nico

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 ;-).

Never trust an operating system you don't have sources for. ;-)

I also have no idea. Possibly this is a gcc issue still? Should I ask
there instead?
