What would be the correct behaviour for non-native binaries?  Stacy Son and Brooks Davis have been working on providing a kernel activator for QEMU user mode, which lets us run, for example, MIPS or ARM binaries on x86.  If you have a MIPS64 ELF file and you run ldd on it, what would the correct behaviour be?
