vlc/vlc-3.0 | branch: master | Rémi Denis-Courmont <remi at remlab.net> | Mon Feb 12 19:00:11 2018 +0200| [3b9799f78de196103db83665acaaf0ecded7f494] | committer: Rémi Denis-Courmont

configure: pipe2 and accept4 are NOT Linux-specific

While both system calls originate on Linux, they are part of POSIX.next
and implemented by FreeBSD 10.0 and other OSes.
