Perhaps we can do something with the FEATURE_DUMP. It'd be nice to
detect build argument changes and rebuild when that occurs. I'm used
to doing lots of `make clean` due to sanitizer builds, something we
should probably capture through features and/or `perf version
--build-options`. Anyway, out-of-scope for these patches.

I need to cut a v2 due to failing to add the new `.a` files to the clean target.

Thanks for the review,
