cross-localedef-native: add way to specify which locale archive to write

localedef has no way to specify which locale archive to use, and the
compile-time default isn't useful as it points to the work directory.

Add support to read an environmental variable for the path, and don't fail to
write a new locale archive.

+localedef --add-to-archive uses a hard-coded locale path which doesn't exist in
+normal use, and there's no way to pass an alternative filename.
+
+Add a fallback of $LOCALEARCHIVE from the environment, and allow creation of new locale archives that are not the system archive.
