Be careful, though, that you need a way to obtain the 'source' address 
of the .rel.dyn start and end and of the .dynsym start, plus the offset 
from 'source' to 'target'; these may not be easy to compute in C

I think the right balance might be to have an ASM framework to prepare 
these four values and pass them to the C relocation routine.

Note that you may also have to make sure the routine itself is 
insensitive to relocation too.

Amicalement,
