   What to do:

       gcc -c reloc.c

       objdump -r reloc.o 

		RELOCATION RECORDS FOR [.text]:
		OFFSET           TYPE              VALUE 
		0000000000000006 R_X86_64_PC32     x-0x0000000000000008
		0000000000000010 R_X86_64_PC32     x-0x0000000000000008

       objdump -d reloc.o

		Disassembly of section .text:

		0000000000000000 <f>:
   		0:	55                   	push   %rbp
   		1:	48 89 e5             	mov    %rsp,%rbp

                              ^^^^^^^^^^^
                              addr 6 (hex)
   		b:	00 00 00 
   		e:	c7 05 00 00 00 00 07 	movl   $0x7,0x0(%rip)        # 18 <f+0x18>
                              ^^^^^^^^^^^
                              addr 10 (hex)

  		18:	c9                   	leaveq 
  		19:	c3                   	retq  

        Depending on where the linker put the variable x,
	These locations must be updated accordingly
