x86-64: Check relocations with -z nocopyreloc
On x86-64, when -z nocopyreloc is used to build executable, relocations
may overflow at run-time or may not be resolved without PIC. This patch
checks these conditions and issues an error with suggestion for -fPIC.

* elf64-x86-64.c (elf_x86_64_relocate_section): Check for
R_X86_64_PC32 relocation run-time overflow and unresolvable
R_X86_64_32S relocation with -z nocopyreloc.
