You are mixing packages from different sources which are not configured in
a way to inter-operate well.  You are not giving enough instructions to
even reproduce the issue - _what_ are you building, _what_ packages exactly
do you have installed.  Your quoted failure doesn't use cross-avr-binutils
from Leap or devel:gcc.

So please use an AVR toolchain from a _single_ source and then specify what
source you used because only then the appropriate people can look at the bug.

I am only responsible for what is in Leap/Tumbleweed and devel:gcc and this
combination works.  (well, there's no avr-libc in Leap IIRC but you can
use the one from devel:gcc when you use cross-avr-gcc version >= 7)

So - if you don't like WORKSFORME then let's have this bug assigned to the
appropriate people (devel:gcc WORKSFORME).
