xtensa: add support for the Xtensa architecture
PATCH v3 1/2 xtensa: add support for the Xtensa architecture
The Xtensa architecture had been removed because it required special handling and depended on additional directories and files that became obsolete over time. This change is more aligned to other architectures.

Actually, these dependencies can be removed again, because perl no longer
depends on host-qemu. I'll post a patch removing them.
And anyway, host-qemu exists for xtensa, no?

Yes, there is a version of Qemu that was done my Max, but it might require a different processor configuration than what's in the toolchain by default.
