I've noticed that this newly added vma-pthread test seems to
be flaky. Here's an example from a clang-user job:
https://gitlab.com/qemu-project/qemu/-/jobs/3600385176

TEST vma-pthread-with-libbb.so on aarch64
fail indirect write 0x5500b1eff0 (Bad address)
timeout: the monitored command dumped core
Aborted
make[1]: *** [Makefile:173: run-plugin-vma-pthread-with-libbb.so] Error 134

and another from a few days earlier:
https://gitlab.com/qemu-project/qemu/-/jobs/3572970612

TEST vma-pthread-with-libsyscall.so on s390x
fail indirect read 0x4000999000 (Bad address)
timeout: the monitored command dumped core
Aborted
make[1]: *** [Makefile:173: run-plugin-vma-pthread-with-libsyscall.so] Error 134
