Would you mind also just making this whole logic (that is generic and 
shared with all the different arch versions) be an inline function of its 
own?

so that all the functions could just use some generic

	location = reloc_location(elf, rsection, r);

or similar, instead of having that complex thing duplicated three times 
(arm, mips and i386)?

Especially since other architectures will likely end up doing the same 
thing too...
