The targets used the plain `$ARCH` triple, which LLVM normalizes to `$ARCH-unknown-unknown`, which is inconsistent with the the other VxWorks targets which all use `$ARCH-unknown-linux-gnu$ABI`.

Same here, r=me if the target maintainer is on board with the change. |

@rustbot blocked (waiting to hear back from target maintainers, not much for me or PR author to do) |

The target triple passed to compilers in vxworks is riscv32 and riscv64, but with numerous flags. I'll test the changes and let you know if unknown linux gnu target is compatible for these targets. |

Rollup merge of rust-lang#138427 - madsmtm:vxworks-llvm-target, r=jieyouxu Fix RISC-V VxWorks LLVM target triples The targets `riscv32-wrs-vxworks` and `riscv64-wrs-vxworks` uses the plain `$ARCH` LLVM triple, which LLVM normalizes to `$ARCH-unknown-unknown`, we should use `$ARCH-unknown-linux-gnu$ABI` which is consistent with the the other VxWorks targets. Motivation: To make it easier to verify that [`cc-rs`' conversion from `rustc` to Clang/LLVM triples](rust-lang/cc-rs#1431) is correct. Alternative: Pass `$ARCH-unknown-none` in the other VxWorks LLVM triples, I don't know anything about VxWorks, so am unsure which is the most correct option. CC target maintainer `@biabbas.` r? jieyouxu
