mk: Add support for musl-based builds This commit adds support to the makefiles, configuration script, and build system to understand MUSL. This is broken up into a few parts: * Any target of the form `*-musl` requires the `--musl-root` option to `./configure` which will indicate the root of the MUSL installation. It is also expected that there is a libunwind build inside of that installation built against that MUSL. * Objects from MUSL are copied into the build tree for Rust to be statically linked into the appropriate Rust library. * Objects for binary startup and shutdown are included in each Rust installation by default for MUSL. This requires MUSL to only be installed on the machine compiling rust. Only a linker will be necessary for compiling against MUSL on a target machine. Eventually a MUSL and/or libunwind build may be integrated by default into the build but for now they are just always assumed to exist externally.

Make sure rsbegin.o and rsend.o get packaged with target lib artifacts. Also, unified libc startup objects finding logic with that of the `-musl` target, since conceptually they were doing the same thing.

mk: Fix dependencies of unwind crate on musl The libunwind.a library was accidentally only being included for the standard library, not the new unwind crate which implements an unwinder.
