“The crash binary can only be used on systems of the same architecture as
the host build system.”
This statement on first read made me think that crash running on particular arch can
handle vmcore of that arch only.

The point is that regardless whether the target vmcore is from
a different architecture, the "alternate" crash binary that is
built with "make target=XXX" must match the architecture of the
host.
