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.
