[Buildroot] [git commit] dt: add patch to fix failures on newer toolchains

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=facda719099f53b8b79efcd6966d4cfe8ffd2719
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

On newer toolchains (glibc >= 2.20) _BSD_SOURCE behaviour was deprecated
in favour if the _DEFAULT_SOURCE macro. See man 7 feature_test_macros.
Add patch from Fedora to also consider _DEFAULT_SOURCE. Fixes:

+_BSD_SOURCE was deprecated, hence switch to use _DEFAULT_SOURCE as well
+to avoid the build from breaking on newer toolchains.
