`aarch64-unknown-linux-pauthtest`, a target that enables Pointer Authentication Code (PAC) support in Rust on AArch64 ELF based Linux systems using a `pauthtest` ABI (provided by LLVM) and pauthtest-enabled sysroot with custom [musl](https://github.com/access-softek/musl), serving as a reference libc implementation.

Based on the todo it seems like you may already be aware, but targets need to be added to rustc first as no-std. After that happens you can bring up libc, then std. How much does the fork deviate from musl? If it’s identical but built differently, it may be worth considering setting ‘target_env=“musl” |

Description
This PR adds support for
aarch64-unknown-linux-pauthtest, a target thatenables Pointer Authentication Code (PAC) support in Rust on AArch64 ELF based
Linux systems using a
pauthtestABI (provided by LLVM) and pauthtest-enabledsysroot with custom musl, serving as a reference libc implementation.
Please consult a rust-lang PR for the details on the target: TODO JKB Add link
Sources
This target reuses the existing musl implementation paths in libc and does not
introduce new platform-specific APIs.
aarch64-unknown-linux-pauthtestshouldbe treated as musl-compatible.
