commit: http://git.buildroot.net/buildroot/commit/?id=22cb51e1a2cdff07f220d7519d05934f6ce1bf2c
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Add rngd.service for systemd. Also patch rngd with patch from Fedora to
ignore failure if no hwrng present:
https://bugzilla.redhat.com/show_bug.cgi?id=892178
[Thomas:
- rename patch to the proper naming convention
- add description and SoB to patch
- install service file to /usr/lib/systemd and not /lib/systemd
- use a relative symbolic link instead of an absolute one]

+Exit with a special value when RNG modules are not available
+
+Instead of returning with an error, exit with a special value when the
+RNG kernel modules are not present in the kernel. This is not really a
+hard failure.
+
+Patch borrowed from Fedora, at
+http://pkgs.fedoraproject.org/cgit/rng-tools.git/tree/rngd-exit-code.patch.
