Subject: [PATCH] lib/crypt: uClibc-ng doesn't set errno when encryption method
 is not available

Since commit [1] in cpython, an exception is raised when an encryption method
is not available. This eception is handled only if errno is set to EINVAL by
crypt() but uClibc-ng doesn't set errno in crypt() [2].
