I just skimmed through the patches, but it indeed looks a lot more
reasonable than the support we originally had for Xtensa, thanks for
this work!. One thing that should be added is to make sure that the
Crosstool-NG backend cannot be selected for Xtensa, as it doesn't
support this architecture.

Also, the issue we had with the original Xtensa implementation is that
the original submitters sent some patches that we merged, and
subsequently never maintained them. Do you have plans to use this
Xtensa architecture on a regular basis, and help us fixing build issues
related to this architecture? Of course, we don't require you any sort
of strict commitment or anything like that, I'd just like to know how
much you'll be using this architecture.

Thanks again for having worked on this,

Thomas
