    It is small (16 B) and therefore the overhead of exporting it more
    than outweighs the size savings from not having duplicated symbols:
    When the symbol is no longer avpriv, one saves twice the size of
    the string containing the symbols name (2x30 byte), two entries
    in .dynsym (24 bytes each on x64), one entry in the importing libraries
    .got and .rela.dyn (8 + 24 bytes on x64) and two entries for the
    symbol version (2 bytes each) and one hash value in the exporting
    library (4 bytes).
    (The exact numbers are of course different for other platforms
    (e.g. when using dlls), but given that the strings saved alone
    more than outweigh the array size it can be presumed that this
    is beneficial for all platforms.)
