Just the binutils patch, as far as I remember.

Evolved a bit, but most of it should be correct.

OK, I've rebased what I'd had in OE branch and if I've not messed up something 
it should be currently in "rik/amd64" branch. Will check if there is anything 
interesting left in overlay of x86_64 project which from this patchset 
originated (project itself was released in May and almost not touched since, 
so I had little incentive to continue pushing this changes, unfortunately). 

Feel free to try/test/enhance with new glibc/gcc versions/corrections, etc. 
I'll probably try to add some new glibc versions on weekend, if time permits. 
I think the first 4 patches are ready for review/push (although need to test 
after rebase), and others mostly need porting to other versions.
