Research direction

Start by comparing the cpufeatures implementation with the referenced std_detect files: detect/os/aarch64.rs and detect/os/freebsd/auxvec.rs. Determine which approach applies to FreeBSD/aarch64, then verify that CPU feature detection works on that target without regressing the existing arm32 and powerpc64 paths.

Written by the indexing model from the issue text.

Description

std::detect uses userspace mrs on FreeBSD/aarch64 as well as having auxval code that's currently used on arm32 and powerpc64 that would work too.
One of these ways should be used here as well… (this is a TODO for myself I guess)
