This setting is not enabled by default and there is no command line switch to
enable this at least in ld 2.39

$ i686-w64-mingw32-ld --version
GNU ld (GNU Binutils) 2.39

$i686-w64-mingw32-ld --target-help | grep nxcompat
  --[disable-]nxcompat               Image is compatible with data execution

$ i686-w64-mingw32-ld --target-help | grep entropy
