Check branch displacement overflow in x86-64 PLT entry
Displacement of branch to PLT0 in x86-64 PLT entry is signed 32-bit.
This patch adds a sanity check. We will only see the failure when PLT
size is > 2GB.
* elf64-x86-64.c (elf_x86_64_finish_dynamic_symbol): Check
branch displacement overflow in PLT entry.
