Clean up improper dependencies on gettext without LOCALE

This series cleans up redundant dependencies on gettext, in packages that select gettext when LOCALE is not enabled.

Patches 1-6 fix the dependency for packages that don't have to be linked with gettext if LOCALE is not selected.

Patch 7 and 8 are examples of packages that depend on libglib2,
