Doh, indeed. How could I miss that? Actually I know, the diff was basically all 
deletions followed by all additions so I focused on common sections.

Anyway both sections (.got and .got.plt) have same access rights (WA) and the 
names shouldn't matter so does glibc changes it's behaviour if there is more 
than one section with (dynamic) relocations? Or does it check if a section is 
full of JUMP_SLOT only?

I'll enable lazy relocation as part of the refactoring I'm doing as it's easier 
but will try to do an intermediary push as soon as I do it rather than wait to 
complete all the refactoring.

Cheers,

Thomas.
