"disable this option" may sound easier than it is. I for one can't think of
a good way to filter out such pretty special cases. Much of ld's cross-
format linking may be limited to "known good" cases, without others getting
explicitly rejected. Furthermore, even "assumed good" cases like ELF->PE on
x86 of course have meaningful restrictions on what the input objects may
legitimately contain. All of this is, I fear, pretty much a grey area.
