some tests fail on all architectures but amd64

[anbe42]

We are running the tests during the Debian package build, but so far we had to ignore the results on all architectures but amd64 since some tests are always failing.
Full build logs including testsuite runs with backtraces for failures are available from https://buildd.debian.org/status/package.php?p=spirv-llvm-translator-15
E.g. on arm64 these 48 tests fail:

@anbe42 thanks for the report, may I ask you to share log for the failed tests? Is it something repeating from test to test or each of the failures is unique?
