[Buildroot] [git commit] uclibc: backport upstream patch adding fcntl definitions on OpenRISC

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=7fb6fe883a6ee360aa861fdae93d7441f9f5d52d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

A number of fcntl.h definitions were missing on OpenRISC in uClibc-ng,
causing build failures such as:

gfile.c: In function 'splice_stream_with_progress':
gfile.c:3017:35: error: 'F_SETPIPE_SZ' undeclared (first use in this function)
   buffer_size = fcntl (buffer[1], F_SETPIPE_SZ, 1024 * 1024);

This comit backports a patch that was merged in upstream uClibc-ng,
which addresses this problem.

Fixes:

+Subject: [PATCH] or1k: add F_{DUPFD_CLOEXEC, SETPIPE_SZ, GETPIPE_SZ}
+
+Those definitions exist on all other architectures, but were not
+present in or1k specific headers when or1k support was merged.
+
+On the kernel side, their support is completely architecture
+independent, so we just need those definitions to make those fcntl()
+calls available on or1k.
