The cross-avr-gcc6 from devel:gcc does work this test case.
Also the new naming is technically more correct for the avr case so I guess
this can be closed.
As mentioned earlier same problem would exist for cross-armv*-gcc6 as well but
I am not particularly concerned at this moment.
Also as the cross-avr-gcc (without suffix) symlink package is not generated
using this compiler is needlessly challenging. Should I open separate bug for
that?
