rustc: new virtual package The compiler for the Rust programming language is called rustc. There is only one reference implementation for it, based on LLVM, from the Rust project [1]. It can generate code for various architectures so it can be labeled as a cross-compiler. But, as for GCC, building it from source takes time. So it would be sensible to have at least one package which provides it as a pre-built version, fetched from the upstream project. Later another package can be added, to build it from source code. In addition to the compiler, the standard library for the host and/or the target should also be fetched/built. So, add a virtual package named rustc to enable support for multiple providers. Currently, only the host variant will be available to allow the user to cross-compile Rust programs for the target.

rust: modify Rust packaging to be usable as host-tool only This commit modifies the host-rust virtual package to default to host-rust-bin when no other selection has been made, as long as the host supports rust. This allows host only tools to still use rust when the target architecture does not support it. Add target-specific variable which is used to differentiate host and target arch requirements (BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS). A target package shall depend on this variable where a host package will use the previously defined BR2_PACKAGE_HOST_RUSTC_ARCH_SUPPORTS. The new "target" version is selectable for the same set of architectures as before, but now depends on the host variant.

package/rustc: install cargo config as toolchain post-install hook The cargo config file is much like the cmake and meson configuration files, something that tells the cargo build system how the cross-toolchain is configured. It is currently installed by the cargo package, but this package is about to be removed as cargo is now built as part of rust itself. Therefore, install the cargo config file as a toolchain post-install hook, just like we do for cmake and meson. However, we don't have a pkg-cargo infrastructure (yet) so we can't put it there. Therefore, put it in the rustc package - any cargo package will need rustc.
