[AMDGPU][test] Define local symbols used in amdgpu-relocs.s

[MaskRay]

This attempts to make the test more "genuine": compilers don't create local undefined symbols.

Do you need -DAG? I would expect strict order for these symbols I think.

[MaskRay]

Delete -DAG

By default, "the output shall be sorted alphabetically by symbol name" (POSIX behavior). I just deleted -DAG

[grimar]

This LGTM.
