localedef failure with -v option

[Lefteris Dimitroulakis]

hello lfsdevs
Using -v option with localedef is failing emitting
"no output file produced because warnings were issued".
This is happening during the build of svn-lfs or stable-lfs
and on a finished lfs system as well.
My question is how safe can we feel if this
happening during the build of
apparently every possible locale?

regards
Lefteris
