From: Pino Toscano <pino@debian.org>
Bug: #656880

# * hurd_shm_flock.diff
# This patch disables all the methods for shared memory and file locking
# found by the configure checks, forcing the only working ones.
# This patch should stay Debian-specific, as it is not that suitable for
# upstream inclusion. (As you can guess, ideally all of those
# non-working methods should be ideally fixed in Hurd...)
