Because, when a mergeable section doesn't contain any relocations, I don't
see any point in making it comdat. Because mergeable sections themselves
are garbage collected, if some constant isn't referenced at all, it isn't
emitted, or if referenced, multiple copies of the constant are merged (or
for mergeable strings even string tail merging is performed).
