Other objects can never reference the MergedGlobals symbol so external linkage is never needed. Using private instead of internal linkage means the object is more similar to what it looks like when global merging is not enabled, with the only difference being that the merged variables are addressed indirectly relative to the start of the section they are in. Also add aliases for merged variables with internal linkage, as this also makes the object be more like what it is when they are not merged.
