WITHOUT_NLS is deprecated use NLS option instead

[Doug Barton]

Tonight I'm seeing this during ports builds:

/!\ WARNING /!\
WITHOUT_NLS is deprecated use NLS option instead

This is silly.

I traced the message to bsd.sanity.mk, which has similar silliness for 
many other longstanding make.conf options. If y'all are clever enough to 
create silly warning messages deprecating options that have been in use 
longer than most of you have been part of the project, you're also 
clever enough to make compatibility shims to cause WITHOUT_FOO to do 
whatever the equivalent behavior is for whatever the options framework 
looks like this week.

Please fix this.

Thanks,

Doug
