erlang (1:14.a-dfsg-3squeeze1) gnu.patch

gnu.patch by Aurelien Jarno <aurel32@debian.org> and
Sergei Golovan <sgolovan@debian.org>

(1) Defines GNU macros not only for Linux but also for any system
    with 'gnu' substring in OS name. Fixes FTBFS on GNU/kFreeBSD and GNU/Hurd.

(2) Undefines BSD4_4 for os_mon application for GNU/Hurd;

(2) Skips building SSL certificate examples for GNU/Hurd (Debian GNU/Hurd has
    no a random translator yet).
