Using DYLD_FALLBACK_LIBRARY_PATH means we first try to link to the normal libraries and only fallback to looking up symbols in gstreamer if the symbols were not found elsewhere. This prevents some linking issues. Testing: Covered by existing tests. Fix for issue #37811 manually verified by the reporter. Signed-off-by: Jonathan Schwender <schwenderjonathan@gmail.com>
