No, you just need to build a musl based cross compiler and then build
_another_ musl based cross compiler with the first one. (Basically a
canadian cross except you use the same target twice.)

The trick is disabling gcc's "oh, I'm native compiling, let me do a
half-assed job" detection logic, which is why I had
"x86_64-unknown-linux" and "x86_64-walrus-linux" targets when I did it.
So the tuples wouldn't match. :)
