[PATCH v4 0/7] linux-user: Add support for various missing netlink sockopt entries

[deller@kernel.org]

From: Helge Deller <deller@gmx.de>

This patchset adds various missing sockopt calls, so that qemu linux-user
is able to successfully build the debian gupnp package in a chroot.

Tested with a 32-bit big-endian hppa linux-user chroot running on a phyiscal
x86-64 little-endian host.

This fixes debian's bug report:
