Description
During my battle yesterday trying to compile rr for cuttlefish arm64, I realized that a simple test binary that just tests for needed perf counters and CPU architecture might save a lot of time before investing effort into getting a full rr build working. We could compile this as a statically-linked PIE with musl, so the same binary could run on almost anything as long as the architecture matches (e.g. Android).

Thoughts? A "better" solution would be to get rr compiled properly for more target platforms, but that is often more work (which may or may not be useful in the end if it's unsupported).

Research direction
Start by reviewing the proposed test binary scope and the linked musl-cross-make project. Determine which perf counters and CPU architectures must be checked and whether a statically linked PIE can run on the stated targets. Done means the project has an agreed implementation and validation plan for this preflight binary.
