Thanks for the notice - I didn't see this email until now, but saw the
related discussion on HardenedBSD's IRC channel this morning.

Note that FreeBSD ar is different from ELF Tool Chain's ar; the latter
is a fork of FreeBSDs, and there are some distinct bug fixes or
improvements in each version that are not present in the other. Here
FreeBSD's ar is buggy, and llvm-ar, GNU ar, and ELF Tool Chain's ar
all return a non-zero exit code.

Code review with fix for FreeBSD's ar: https://reviews.freebsd.org/D31402
