gst-plugins-ugly builds against opencore-amr and libcdio.
Add those optional deps to be specific and consistent.
gst-plugins-ugly fails to compile when `opencore-am?b` are
installed due to missing includes. Add the location of them
to the appropriate env vars. Tested on ML with clang and llvm
from XCode-4.4.1.
