If we leave the target mode as big-endian, we need to teach the elfloader to handle binary of reversed endianness.  I have looked into that possibility as well but find the current approach easier.

Byteswapping logic is reversed also when QEMU is running in that mode.

I can't say I'm a huge fan of this patch. It allows for really tricky subtile mistakes to happen. Can't we leave the target mode configured on big endian?
