Issue first shows up on gcc-11 with these types of library symbols:

     U Foam::tableReader<double>::dictionaryConstructorTablePtr_[abi:cxx11]
  xx B Foam::tableReader<double>::dictionaryConstructorTablePtr_

  Use concrete hasher functor for runtime selection tables, which
  avoids any additional template resolutions (introduced with
  95cd8ee7). The library symbols now resolve _without_ an
  additional abi:cxx11 tag.
