which means no avr.  Our binutils are configured with
--enable-targets=aarch64-suse-linux,alpha-suse-linux,armv5l-suse-linux,armv6l-suse-linux,armv7l-suse-linux,armv8l-suse-linux,hppa-suse-linux,hppa64-suse-linux,i686-suse-linux,ia64-suse-linux,m68k-suse-linux,mips-suse-linux,powerpc-suse-linux,powerpc64-suse-linux,powerpc64le-suse-linux,riscv64-suse-linux,s390-suse-linux,s390x-suse-linux,sh4-suse-linux,sparc-suse-linux,sparc64-suse-linux,x86_64-suse-linux,xtensa-suse-linux,powerpc-macos,powerpc-macos10,spu-elf,x86_64-pep 

lacking avr (not sure why we not simply do --enable-targets=all).

Micha? Andreas?  Adding avr to this list is easy (we should at least have
all enabled that we build cross-binutils packages for I guess, epiphany
is also missing).
