How do you know it’s this line?

The “Failed to set a socket option” would make me think it’s about a
failing setsockopt(2) call, but it’s not supposed to return ENODEV.
socket(2) is not supposed to return ENODEV either.

Could you keep the failed build directory (with ‘-K’), and from there
run the test in ‘strace’ to see exactly what’s failing?  (With the
caveat that it may succeed outside the build environment; did you try
running ‘make check’ from the failed build tree, outside the build
environment?)

It will!  :-)
