`hexagon-unknown-linux-musl` target linking generate misaligned/broken binary

Rust nightly -Z build-std and -W linker-messages
hexagon-unknown-linux-musl target binary can't be run.

warning: linker stdout: Misaligned constant address: 0x80000006 has alignment 2, but the memory access requires 4. The instruction has been replaced with a trap.

I think rust should enable -W linker-messages by default, for better telling programmer some hidden warnings which can incur broken/crashed binary.

Start by reproducing the hexagon-unknown-linux-musl build with nightly -Z build-std and -W linker-messages, then inspect the emitted misalignment warnings and resulting binary behavior. Determine whether the linker warnings should be enabled by default and verify that the target binary no longer becomes un runnable or that the warning behavior is clearly covered.
