--- Comment #9 from Jason A. Donenfeld <jason at zx2c4 dot com> ---
This problem still exists on binutils 2.33 when -fvisibility=hidden is passed
to cflags. I imagine this is so due to some conflicting code where the forced
B.W is only generated for static functions, since non-static ones will be
relocated differently, but then because of -fvisibility=hidden, they get
treated like statics, only B is used instead of the forced B.W, causing this
issue to crop up again.

OpenWRT experienced this when including WireGuard on a new board. I fixed it
like this:
