[avr-libc-dev] 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:

Cheers,
Nico
