Work around an issue found when working with gcc3 on alpha,
gcc2 nomally calls functions thru the gp (basically a function pointer), but gcc3 frequently calls directly to the plt. gcc2 does occasionally directly call to the plt. Currently how the plt/pltgot is fixed up on lazy binding, this will cause the dl_bind code to be called on each plt call causing a symbol resolution and plt fixup. This diff works around the problem partially by recognizing that a pltgot entry is already fixed and skips the symbol resolution. Since the pltgot is what is modified do not add PROT_EXEC permission to the mapping. While this is not an ideal fix, kettenis and I think it is better than before.
