Clang does not support '-mno-riscv-attribute' resulting in the error error: unknown argument: '-mno-riscv-attribute'
This appears to conflict with your subject, which cities gcc, but I suspect that's due to poor wording of the body of the commit message than a mistake in the subject. I'd rather disable rust on riscv when building with gcc, I've never been satisfied with the interaction between gcc and rustc's libclang w.r.t. extensions.
Cheers, Conor.
Not setting BINDGEN_TARGET_riscv results in the in the error error: unsupported argument 'medany' to option '-mcmodel=' for target \ 'unknown' error: unknown target triple 'unknown'
