It does?  That doesn't sound right.  It would make protected symbols
useless in shared libraries.  I don't see it happening in, e.g.,
protected_1.so in the testsuite.  Where do you see that?

Symbols with hidden and internal visibility are forced to STB_LOCAL in a
final link, but not protected symbols.  Gold does that because that is
what the ELF ABI specifies should happen.
