armv6kz-linux-musleabihf

[andrewrk]

This is the architecture of raspberry pi zero: I think this is happening because it should be soft float not hard float.

./build -j1 arm-linux-musleabihf -mcpu=generic+v6kz

It fails when configuring cross LLVM with:

I don't think this is a particularly interesting target.
