To be fair, typical cause of occurrence of the second unversioned symbol in the
readelf -a output is due to the presence of the static (debugging) symbol
table.
It is not used for dynamic symbol resolution, so really only one environ is
exported.  That said, it is wrong for environ to be exported with any
version, as well, it must be unversioned in the dynamic symbol table.  Our
rtld is forgiving but in principle we could check.
