This happens during make distcheck.  It is two issues.

First the new test files weren't in EXTRA_DIST causing them to be not
available after make dist. This is fixed by the fist attached patch.

Second when building with the gcc undefined checker (configure
--enable-sanitize-undefined) the sanitizer finds one issue that is
undefined:

libcpu/riscv_disasm.c:457:57: runtime error: left shift of negative value -1

The issue is that the left shift is done on a signed value.  Simply
changing the context to be unsigned (as is done in the rest of the
code) fixes this. This is the second attached patch.

Note that the s390x builder was just taken offline for repairs. It
should come back online later this weekend. So it might take a bit for
the builder to be completely green again.

Cheers,

Mark
