Applied, thanks. I must say I'm not super happy with having such large
patches, especially as they will only disappear when we get rid of the
corresponding binutils version. But oh well, it's on the other side
really nice to see that you're maintaining the xtensa support in
Buildroot on a regular basis, and it's probably needed to have a proper
support for this architecture.

Thanks again!

Thomas
