It's the case for i386, amd64 and arm EABI at least. The first patch I 
proposed only assumed that it's aligned on 2 bytes at least for arm which was 
true. But indeed, this new version assume it's the case for all architectures. 
Can c67, il or arm OABI GOT entries be byte aligned? If yes, I'll use the 
first version of the patch.
