Fixed by https://codereview.qt-project.org/113558 for Linux. No fix for non-
Linux (not relevant).

    The big advantage of an ELF version is that, when we do Qt 6, both
    versions of QtCore could be loaded in memory without conflicts and all
    symbols would be resolved to the correct library. No module can talk to
    both at the same time, but this avoids mistakes of loading them
    indirectly by plugins.
