freeBSD 12.2-RELEASE not working #431
Description
Even though it seems there is logic to push a freeBSD binary to the releases page, there doesn't seem to be one there. (Unless I'm just missing it).
However, running a stock 12.2 release system FreeBSD fbsd12.2-build 12.2-RELEASE FreeBSD 12.2-RELEASE r366954 GENERIC amd64, I downloaded the latest py-spy source (3.8 at time of writing) and compiled without any problems. However, if I run the program I get this:

I'm just starting a standard interpreter session, nothing fancy.

I also tried on another freebsd machine 12.2-RELEASE-p6 trying to profile a complex long-running python program (version python 3.9.5) and get this instead

Not sure if I'm doing something wrong, but seems like all documentation points to freeBSD being supported so I'm assuming the issue is me 😄
