this is an architecture specific question so you should say which
target you are talking about.

musl officially only supports linux userspace, but a lot of code
in it should work unchanged in kernelspace or baremetal environment.
but you are on your own to figure out how to make that work.

not sure what trouble you have with address translation, but that's
either outside the scope of the libc or part of the crt startup code
that sets up the runtime environment on a baremetal system.
