glib: remove gettext-native dependency for native builds
By removing gettext-native as a build dependency in glib-2.0-native we can delay
the build of gettext-native further. The gettext class will add the dependency
for target builds.
Don't forcibly set USE_NLS=yes so that NLS support is supposedly disabled in
native builds. GLib will then force it back on, but we shouldn't be using it in
any other native recipes so seed the autoconf cache so GLib will run /bin/false
instead of msgfmt. Quite a kludge, but it works and should fail obviously if
the kludge stops being sufficient.
