buildkeys when trying to determine if the plugin is compatible

-work around iconv(3) incompatibilities: while NetBSD's iconv() is
probed as GNU iconv (due to its signature), it doesn't support empty
strings as encoding (interpreted as "current locale's encoding" by
GNU iconv). Enable some code which uses nl_langinfo(CODESET) to make
it work as expected.
-update to 4.3.1
changes:
-bugfixes
-Updated the German translation to provide complete coverage of Qt
