luajit-2.1.0~beta3+git.1624618403.e9577376-150400.4.2.1

- Replace luajit-ppc64-remove-asserts.patch with
  luajit-ppc64-replace-asserts.patch to use the proper assert
  functions instead of removing them.

- Add luajit-ppc64-remove-asserts.patch: remove calls to
  lua_assert. Fixes the build with our revision (bsc#1191615).
- Add luajit-s390x.patch: add s390x support, based on Fedora's
  patch and ported to our revision.
- Remove ExcludeArch, since package currently builds on s390x.

- Exclude s390x for now. There is a not-yet-upstreamed port
  available, but we would need to rebase it for our release.

- Clean up SPEC. We don't need update-alternatives after all.
