I am not sure what kind of compatibility we will need to preserve for libcrypto. For sunrpc 5500cdba401), we have removed most of the symbols but still kept some old ones for compatibility even though the libtirpc does implement such symbols (like key_setsecret for instance). It seems that libcrypto is way simpler, and libxcrypt does implement all require symbol version which the expected.

The idea of the patch is to streamline the required build coverage to avoid having a --enable-crypt just for sparc. Sure we can pack if/when we remove libcrypto, but I think this is orthogonal.

You feel strongly so it's fine with me to yank it then, I just felt it was cleaner to not "soft-kill" it before it was removed, but you're right that it's unclear how we're even going to remove it and how far. Objection withdrawn - thanks!
