Ah, I know understand what you are trying to achieve - No, my code does
not allow for in-flash relocation.

My code processes the ELF relocation structures rel.got (which has pointers
into .got), got.plt (which is where the location of .got is retrieved at
run-time), rel.dyn (pointers into other sections other than .got), .dynamic
and .dynsym

I must admit, I do not know why there are so many sections which need to
be patched - I originally thought that only .got would need modifying, but
the rabbit-hole is much deeper
