This fails to compile on the FreeBSD 12 and 13 jobs:
https://gitlab.com/qemu-project/qemu/-/jobs/3479763741
https://gitlab.com/qemu-project/qemu/-/jobs/3479763746

The compiler is producing -Wthread-safety-analysis
warnings on code in qemu-thread-posix.c, which are a
compile failure because of -Werror.
