Add flag to disable the voltab section in the generated library, which (if present) appears to break mingw-w64 linking. See: ocaml/ocaml@0ac7358 and matthew-brett/dll_investigation#1 (comment)

This should disable the voltab section in the generated DLL, which appears to break mingw-w64 linking. See: ocaml/ocaml@0ac7358

xref #20880. This buys us a little breathing room and could allow using the current vs2019 toolchain for wheels. |

The comment on the ocaml commit says
I think the risk is acceptable. |

Right - the risk is only that we continue to get the same emulation performance - for this library specifically - as we would for a VS2017 build. And I suppose there is some hope we will build ARM64 wheels, at some point. |

Also xref current issue building with VS2017 - #21346 |
