--- Description ---
Trying to build graphics/wayland on poudriere FreeBSD-13 / amd64, it fails with
the following error:

ninja: build stopped: subcommand failed.

Previously, during configure, there is this message:

Checking if "MSG_CMSG_CLOEXEC works correctly" compiles: NO

Any idea of a possible cause?
