I don't think this was a good idea at all. Before, bbappends were applied
in the priority order of the layers, but this change throws the sorting
based on priority out the window and might cause bbappend files for higher
layers to be applied before lower layers' bbappend files.
Please revert this change, and rethink how to maintain a stable order for
bbappend files from the same directory without affecting bbappend files
from different layers.
