/* Note: The above jump is hand coded to work around bugs in binutils.
* 5 byte are used for a 3 byte instruction. This works because x86
* is little endian and allows us to use supported 32bit relocations
* instead of the weird 16 bit relocations that binutils does not
* handle consistently between versions because they are used so rarely.
