Maybe a little simpler:
config CONFIG_PASSWD_STRENGTH
 	bool "check  for  weak new passwords"
 	depends on CONFIG_PASSWD
 
so if it is not set we can remove the check from passwd code and 
the full obscure.c code.

What's this for?  I googled a little but have not found a good explanation.

Fixes applied, Thx.

I will repost it in a few days, maybe there will be other comments.
