Comment:
Since the clean has to be run from an authoritative location, it can only clean things that that location is authoratative for.  In the current version there's an ARCHS variable up at the top, which needs to be set to "armv6l armv7l x86_64 i686" in one place "aarch64 aarch64-musl" in another, and "armv7l-musl armv6l-musl x86_64-musl" in a third.
