To make it easier for the maintainer to include more details in the
commit message, I've attached the original build error message below.

  BINDGEN rust/bindings/bindings_generated.rs
error: unknown argument: '-mexplicit-relocs'
error: unknown argument: '-mdirect-extern-access'
error: unsupported argument 'normal' to option '-mcmodel=' for target 'unknown'
error: unknown target triple 'unknown'

- Invalid flag syntax

Also, the `Cc: stable` is indeed targeting 6.12+, as it's the first
LTS with LoongArch64.

Thanks again!
