Hi, I'm trying a few Rust-enabled builds, and I got the following error
when building an arm kernel:

make --silent --keep-going --jobs=8 O=/home/tuxbuild/.cache/tuxmake/builds/current ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- 'CC=sccache arm-linux-gnueabihf-gcc' 'HOSTCC=sccache gcc'
error: unknown argument: '-fno-ipa-sra', err: true
thread 'main' panicked at 'Unable to generate bindings: ()', /root/.cargo/registry/src/github.com-1ecc6299db9ec823/bindgen-0.56.0/src/main.rs:54:36
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
make[2]: *** [/builds/linux/rust/Makefile:229: rust/bindings_generated.rs] Error 1

make: *** [Makefile:222: __sub-make] Error 2

There I'm using LLVM/libclang from Debian 11 (so LLVM 11). Is this
supposed to be fixed by a newer LLVM (assuming that flag got implemented
since then), or should I send a patch to rust/Makefile to filter that
specific flag out as well?
