Rust apps build with gcc, even clang is set up in makepkg.conf

Hi,

I wanted to build rust aplications from AUR with clang. I put this to my makepkg.conf.

CARGO_PROFILE_RELEASE_LTO="thin"
CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_LINKER=clang
RUSTFLAGS="-C opt-level=3 -C target-cpu=native -C linker-plugin-lto -C link-arg=-flto -C link-arg=-fuse-ld=lld"

But if I check apps, I see only gcc.
readelf -p .comment /usr/bin/garbage

String dump of section '.comment':
  [     0]  GCC: (GNU) 11.2.0
  [    12]  Linker: LLD 13.0.1

building rust applications without using some parts of gcc may be impossible until https://github.com/rust-lang/rust/issues/72241 is solved.
