> After the linked LLVM change, the build fails with
> CONFIG_LD_ORPHAN_WARN_LEVEL="error", which happens with
> allmodconfig:
>
> ld.lld: error: vmlinux.a(init/main.o):(.hexagon.attributes) is being placed in
> '.hexagon.attributes'
>
> Handle the attributes section in a similar manner as arm and riscv by
> adding it after the primary ELF_DETAILS grouping in vmlinux.lds.S, which
> fixes the error.
