I hope someone else will be able to suggest a better approach (it would be
interesting for me too), but what I would do is this:

1) create a 386 virtual machine (kvm, vmware, ...)
2) install a 386 fedora (better if you match the version which is on the old laptop)
3) compile in the vm

This will work for sure.

The alternative is "gcc -m32", but if the program is not simple and has
dependencies on libraries, things will get complicated.
