I'm afraid it doesn't build on arm64.

Some of these actually look like non-arch specific failures (e.g.
conflicts with register_t from system headers) or issues which should
probably be addressed with xenalyze in tree (e.g. NR_CPUS ought to be
available directly now?) or with some trivial #ifdef modifications.

That said, I don't know that xentrace actually works on ARM nor that
xenalyze could analyse such traces even with the build issues addressed,
so I'd be equally happy if this was just made x86 only.
