    elf: Use uint64_t for common symbol alignment warning
    
    Use uint64_t for common symbol alignment warning to avoid
    
    elflink.c:5548:12: runtime error: shift exponent 37 is too large for 32-bit type 'int'
    
    with invalid input in PR ld/33500.  Now ld issues:
    
    ld: warning: alignment 137438953472 of common symbol `__afl_global_area_ptr' in pr33500.o is greater than the alignment (8) of its section *COM*
    
    instead of
    
    ld: warning: alignment 32 of common symbol `__afl_global_area_ptr' in pr33500.o is greater than the alignment (8) of its section *COM*
    
            PR ld/33511
            * elflink.c (elf_link_add_object_symbols): Use uint64_t for
            common symbol alignment warning.
