amend powerpc64le_unknown_linux_musl.rs to fix copyright date

This changes the docs referring to where a user should be wary of depending on "Any" trait impls from warning about relying on them "outside" of their code to warning about relying on them "inside" of their code.

Previously, `is_unique` would not synchronize at all with a `drop` that returned
early because it was not the last reference, leading to a data race.

Fixes rust-lang#51780

Update error prompt message to indicate that VS 2017 is supported (for a while now).

rust: add initial changes to support powerpc64le musl

Initial changes to support rustc building on ppc64le with musl. A PR was also submitted to libc component rust-lang/libc#1023 to add changes to libc musl definitions.

A PR was submitted on Alpine alpinelinux/aports#4549 with equivalent temporary patches for building on Alpine for now.

As a verification test a github project was put together to build ppc64le versions of rustc, rust-stdlib, and cargo on Alpine, https://github.com/mksully22/ppc64le_alpine_rust_1.26.2

[cross-lang-lto] Allow the linker to choose the LTO-plugin (which is useful when using LLD)

This PR allows for not specifying an LTO-linker plugin but still let `rustc` invoke the linker with the correct plugin arguments. This is useful when using LLD which does not need the `-plugin` argument. Since LLD is the best linker for this scenario anyway, this change should improve ergonomics quite a bit.
