I believe it is an issue with (a different behaviour of) the
toolchain. I found a machine at $WORK with petalinux 2021.1 and rebuild
zynqmp-pmufw-builder with the following minor patch:

I had to also pass the -m* flags in EXTRA_COMPILER_FLAGS to get it to
link, presumably the petalinux toolchain has incompatible
defaults. Luca, any specific reasons to not pass CFLAGS there?

With this build I do NOT see the exception from the PMU during a reboot.

Notice that this is a gcc10 based toolchain:
