Subject: Do previous in a different way.  We want USE_GNU_ICONV to always use
 a GNU libiconv, whether it be builtin or not, and PREFER_{NATIVE,PKGSRC} can
 be used to decide which iconv we use if USE_GNU_ICONV isn't defined. On
 NetBSD, the native iconv implementation (if it exists) is considered GNUish
 enough unless USE_GNU_ICONV is explicitly defined.
