GNU ld supports `-EL` and `-EB` options to choose a default output format (big- or little-endian). We choose the appropriate endianness based on the format of the input objects and can ignore these options.

We could produce an error if `-EL` / `-EB` did not match the endianness of the input objects, but I don't think it's worthwhile.
