And it doesn't actually help to make micro-libc _less_ onerous to build than compiler-rt builtins, since you also need that...

In my ideal world (which might not be practical!), the user doesn't build compiler-rt at all (they don't even need to know it's a thing) -- they use whatever means they usually do to get clang installed on their system and that's sufficient for them to work on their project. So, to me, asking the user to build a micro-libc or compiler-rt is somewhat onerous in and of itself.
