[Adding (back?) George, which wrote and maintains xenalyze, and tracing
in general, and adding ARM people as well, because this is on ARM,
isn't it?]

That's correct, it's all in tree now.

Mmm... In an x86 build, this is what I get:
(debian-stable_amd64)dario@Solace:/home/SOURCES/xen/xen/xen.git$ ls tools/xentrace/xenalyze -lah
-rwxrwxr-x. 1 dario dario 174K Mar  8 12:36 tools/xentrace/xenalyze
(debian-stable_amd64)dario@Solace:/home/SOURCES/xen/xen/xen.git$ ls dist/install/usr/local/bin/xenalyze -lah
-rwxr-xr-x. 1 dario dario 174K Mar  8 12:36 dist/install/usr/local/bin/xenalyze

I guess we're talking about ARM (cross?) builds, which is something
(especially for tools!) that I really have not much experience with.

Maybe there's more to modify, in terms of Makefile-s, etc., to make
that be build on ARM...

It's not part of any Xen image. It's a command line tool to be used,
usually but not necessarily, in dom0, build and installed together with
the other tools... At least in my case, for x86 builds and installs.
