test_arm64_mem_hook_read_write fails on riscv64 and s390x

[strophy]

I am experiencing the following test_arm and test_arm64 errors after successful build from current master on riscv64 and s390x arch under Alpine Linux 3.21:

Test test_arm64_mem_hook_read_write...          [ FAILED ]
  test_arm64.c:649: Check counter[0] == 4 && counter[1] == 4... failed

and

Test test_arm_mem_hook_read_write...            [ FAILED ]
  test_arm.c:864: Check counter[0] == 2 && counter[1] == 2... failed

Additionally s390x throws errors for test_mem, test_riscv and test_x86, I'll open a separate issue for that if necessary after this one.

Build logs are here: https://gitlab.alpinelinux.org/strophy/aports/-/pipelines/304520
I'm happy to push builds from specific commits through the Alpine CI system when you tag me, or you can do this yourself with a free account.

Building unicorn 2.1.3 on Fedora Rawhide has similar results. A log of the build is available at the URL below. The bottom of the log documents the failing tests.
