Fails to build for aarch64-pc-windows-gnullvm target due to invalid target triple getting passed to clang

[BtbN]

Describe the bug

When building for the aarch64-pc-windows-gnullvm target, building the assembly bits fails due to clang getting passed an invalid target name.
Namely, the rust target has an "llvm" sitting at the end, while the llvm target does not.

To Reproduce

Add the aarch64-pc-windows-gnullvm target via rustup or other means, and try to build rav1e for it.
