WARNING: This email originated from outside of Qualcomm. Please be wary of any links or attachments, and do not enable macros.

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.
