I have some reservations about this series as I've previously mentioned
but I had a try at testing it on the autobuilder:

https://autobuilder.yocto.io/builders/build-appliance/builds/1059/steps/BuildImages_1/logs/stdio

Basically binutils-cross is bust with errors like:

| x86_64-poky-linux-ar: error while loading shared libraries: libfl.so.2: cannot open shared object file: No such file or directory
| make[5]: *** [libaudio_resampler_sse.la] Error 127

There are a ton of other failures, I've not waded through them but I'm
guessing there are similar issues.

Cheers,

Richard
