Revert "[build][rust] Workaround dropped RISC-V target features in LTO"

This reverts commit bf0a761ed46a099b1f312b88e8807f49f5ea980d.


Reason for revert: There needs to be more nuanced handling when passing `-mllvm` flags through Rust's `-Clink-args=` for various platform differences. We can reland when we're certain we handle those cases correctly.

Original change's description:
> [build][rust] Workaround dropped RISC-V target features in LTO
>
> While the clang and LLVM toolchains have a more robust handling of
> target features, the current intree Rust toolchain does not, meaning
> that its possible for the LTO'd modules in RISC-V to have missing target
> features, like setting the floating point ABI correctly.
