Delete comparison with GlobalOffsetTable.

Summary

Now that _GLOBAL_OFFSET_TABLE_ is defined, we can just use R_PC for it
if needed.

Sorry, I git-svn committed it by mistake. Let me know if you think it is broken :-(

It is not completely obvious to me that this is indeed equivalent as the semantics of R_GOTONLY_PC, but it seems to work. I think it works because we define _GLOBAL_OFFSET_TABLE_ as hidden. This no longer forces the creation of an empty GOT but I think the use of these relocation implies that there is a non-empty GOT already.

Benefit of your change as that this will allow us to make _GLOBAL_OFFSET_TABLE_ point somewhere in the middle of the GOT as suggested by the ABI. So let's keep this for now.
