How do you know it=E2=80=99s this line?

The =E2=80=9CFailed to set a socket option=E2=80=9D would make me think it=
=E2=80=99s about a
failing setsockopt(2) call, but it=E2=80=99s not supposed to return ENODEV.
socket(2) is not supposed to return ENODEV either.

Could you keep the failed build directory (with =E2=80=98-K=E2=80=99), and =
from there
run the test in =E2=80=98strace=E2=80=99 to see exactly what=E2=80=99s fail=
ing?  (With the
caveat that it may succeed outside the build environment; did you try
running =E2=80=98make check=E2=80=99 from the failed build tree, outside th=
e build
environment?)

It will!  :-)
