Should we have a workaround for the gas bug or should we change the requirements for 
gas to higher?

I don't see how we could devise a robust workaround: it is my understanding that
the register allocator is free to assign any GP register to the pc_thunk. But you
might want to ask the maintainer of the x86 port.

There's no reason I shouldnt' believe this. But we then need to document 
the requirement on newer binutils, possibly pointing to this particular 
PR. Would you mind, or...?

I was not involved in the analysis phase of this bug so I don't think I'm the
right person to submit a patch.

This is a documentation bug because a binutils (gas) bug that causes this problem.

I've traced the failure to between binutils 2.13 and 2.13.1. 2.13 fails, 2.13.1 works with this 
testcase.

A newer binutils, 13.1 is required now and this is documented for 3.3.1 and the mainline, so 
closing as fixed.
