Official rust risc-v targets are prefixed with riscv32gc- and riscv64gc-: https://doc.rust-lang.org/nightly/rustc/platform-support.html Particularly crossbeam-utils make important build time decisions for atomics based on those names, and so we need to match ours with official targets. On the other hand, the actual definitions for those targets do not use the 'gc' suffix in 'arch' and 'llvm-target' fields, and so we need to follow that too, to avoid cryptic mismatch errors from rust-llvm: https://github.com/rust-lang/rust/blob/master/compiler/rustc_target/src/spec/riscv32gc_unknown_linux_gnu.rs (From OE-Core rev: 2daa8d76369cd06e5c357e393e3145e08f3d6760) Signed-off-by: Alexander Kanavin <alex@linutronix.de> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> (cherry picked from commit 1cfb9c8a59d98ccc9b0510cd28fb933f72fb6b6c) Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
