This commit provides the build flags for Rust for AArch64. The core Rust
support already in the kernel does the rest. This enables the PAC ret
and BTI options in the Rust build flags to match the options that are
used when building C.
The Rust samples have been tested with this commit.

Note that only x86_64 is covered and not all features nor mitigations
are handled, but it is enough as a starting point and showcases
the basics needed to add Rust support for a new architecture.

This script takes care of generating the custom target specification
file for `rustc`, based on the kernel configuration.
It also serves as an example of a Rust host program.
A dummy architecture is kept in this patch so that a later patch
adds x86 support on top with as few changes as possible.
