Ah, thanks for the note. It was not documented in lld's man page; I
just added it upstream.

Just adding LDFLAGS=-Wl,--warn-backrefs to /etc/make.conf should be
sufficient. I'm not sure of the proper way to replace the linker (with
a build from upstream that supports --warn-backrefs) or provide a
custom make.conf in Poudriere though, and hope that someone else can
provide some guidance on that.
