This commit reworks how BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS is defined to more clearly map with the list of platforms supported by Rust as listed at https://doc.rust-lang.org/nightly/rustc/platform-support.html. Indeed, the situation is not as simple as a list of architectures, all supported for both glibc and musl. So instead, we take the approach of directly mapping with what's described at https://doc.rust-lang.org/nightly/rustc/platform-support.html, which means: * A list of Tier 1 platforms (in fact just 3 platforms) * A list of Tier 2 platforms with host tools (i.e where rustc and cargo themselves are available for the target, something that isn't relevant for Buildroot) * A list of Tier 2 platforms with no host tools support. For each platform, we add as a comment its Rust tuple name, as listed at https://doc.rust-lang.org/nightly/rustc/platform-support.html, and then the corresponding Buildroot architecture/libc dependency. This is obviously more verbose than it was, but it is also a lot easier to maintain. With this, a total of 16 new platforms are supported, 13 of which are musl-based. The additional non-musl platforms are ARMv5TE, RISC-V 64-bit and Sparc64. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Yann E. MORIN <yann.morin.1998@free.fr>
