    Revert "Add a test to check for duplicate definitions in the static library"
    
    This reverts commit ff110b2591f0bdeccd121c3726af19c62d6fb184.
    
    I had the wrong cherry-pick reference (the commit content is right; it's
    just referring to a base that isn't upstream), but let's revert and reapply
    for clarity.
