I guess non-native guest would be another way of saying it. There is
some hoop jumping to deal with the fact that some arches package up a
fully featured multiarch aware gdb and some package up the multiarch one
as a separate gdb-multiarch package.

So this is a missing patch from Ubuntu's gdb?

We could just peg the sha1 test to cortex-a57 - your are likely not
getting the SVE tests running unless you have the compilers to build
them (or using docker).
