It seems to work, but not at all optimized for size.
The extra copy of sha256 code need to be removed.
The yescrypt code in libbb/yescrypt/* is adapted from libxcrypt-4.4.38
with minimal edits, hopefully making it easier to track
backports by resetting the tree to this commit,
then comparing changes in upstream libxcrypt to the tree.
