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,
