Functional tests for llvm-custom builds. Each build's bin/ is laid over Google's official NDK toolchain for the same release and tested there: Linux hosts natively or under qemu-user, Windows hosts (x86_64, i686) under Wine.
Run Actions > Test LLVM > Run workflow with the NDK release (r20b, r24-beta1, ...). Each host build is its own job; the summary job lists OK/FAIL/SKIP per host.
The scripts in scripts/ also run locally:
./scripts/test-llvm.sh r24 aarch64-linux-musl
./scripts/test-llvm-win.sh r24
