musl LLVM toolchain

[leoluk]

We may be able to use a static toolchain like this one: https://github.com/grailbio/bazel-toolchain

The Linux kernel is technically able to be built with LLVM, even with CFI (which is nice for security). Google uses it in production and Pixel phones.

This is now a thing, too: https://github.com/aspect-build/gcc-toolchain

Working on this. Trying to build a fully static and portable llvm+clang+libcxx+musl toolchain.

Currently paused because got preeempted by Kubernetes / Control Plane split. But still in my immediate backlog (#145).

Letting someone else deal with this beast.
