Extended Description

This is based on the test case from D75671.

Imagine we have an object with relocations:

(A piece of YAML)
Relocations:

Addend == first negative int64 == -1.

  - Addend: 0xffffffffffffffff
    Type:   R_X86_64_NONE

Addend == min possible int64 == 0x8000000000000000.

  - Addend: 0x8000000000000000
    Type:   R_X86_64_NONE

Addend == an arbitrary negative number.

  - Addend: 0xFFFFFFFFFFFFCFC7 ## -12345
    Type:   R_X86_64_NONE

Currently, we print:

Type Symbol's Value Symbol's Name + Addend
R_X86_64_NONE ffffffffffffffff{{$}}
R_X86_64_NONE 8000000000000000{{$}}
R_X86_64_NONE ffffffffffffcfc7{{$}}

But it does not match to the GNU readelf which prints addends differently:
Type Symbol's Value Symbol's Name + Addend
R_X86_64_NONE -1
R_X86_64_NONE -8000000000000000
R_X86_64_NONE -3039

Probably we want to be more compatible with GNU.
