# DESCRIPTION: GitLab CI/CD for libRetro (NOT FOR GitLab-proper)
#
# Builds armsx2_libretro.so on the libretro buildbot (git.libretro.com mirror)
# for Linux x86_64 and aarch64. Inert on GitHub — the GitHub Actions
# workflows under .github/workflows/ are the project's own CI.
#
# The buildbot containers ship no Clang and none of the pinned third-party
# libraries, so before_script installs clang-17 from apt.llvm.org and reuses
# .github/workflows/scripts/linux/build-dependencies-runner.sh to build the
# same dependency set the GitHub nightly uses (shaderc, SDL3, zstd, lz4, ...).
