I submitted this change in openSUSE and the mingw packages were
rebuilt as a result, so on openSUSE side everything works as expected.
I also checked msys2 and they use the correct configure line so they
use the same ABI as openSUSE.

It would be nice to have this fixed in Cygwin and get all mingw
packages rebuilt as a result.
