Are they used? I am sure we haven't implement all the x86 relocations,
but elf writer is already fairly functional there. I would suggest
doing this one relocation at a time. And start with the simple ones
:-)

For example, first add support for a function that just calls an external one:

------
f:
bl g
------

Also, if only ARM needs support for fancier relocations, we should try
to avoid modifying other targets.
