    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.

        R_X86_64_PC32 relocation run-time overflow and unresolvable
        R_X86_64_32S relocation with -z nocopyreloc.
