compiler-rt: Use FreeBSD's elf_aux_info to detect AArch64 HW features Using the out-of-line LSE atomics helpers for AArch64 on FreeBSD also requires adding support for initializing __aarch64_have_lse_atomics correctly. On Linux this is done with getauxval(3), on FreeBSD with elf_aux_info(3), which has a slightly different interface.
