It is not a bug and not everyone wants the same as you, e.g. you can't refer to
symbols in the PIE from plugins if you do.  When compiling PIE executables, you
shouldn't be using the -fPIC/-fpic flag, but -fPIE/-fpie instead, which works
similarly to -fvisibility=hidden in that references to those symbols are
cheaper (can use GOT/IP relative addressing on many architectures), but the
symbols are still exported.  Please stop reopening.
