> Tentative patch
With this patch, we run into PR24341 for this example:
...
$ cp ../hello-64 1
$ cp ../hello-32 3
$ cp ../hello-32 4
$ dwz -m 5 1 3 4
dwz: Multi-file optimization not allowed for different pointer sizes, skipping
3 with pointer size 4
dwz: Multi-file optimization not allowed for different pointer sizes, skipping
4 with pointer size 4
dwz: 5: .debug_info section not present
...
Another problem is that given that the first file determines the the multifile
pointer size, so 32-bit, there's no point in running in multifile mode because
the other 2 files are 64-bit, so incompatible with the multifile.
