    CTF,BTF testsuite: Use -gdwarf-4 for restrict type qualifier [PR101283]
    
    DWARF DIEs do not contain DW_TAG_restrict_type when DWARF version is 2. CTF/BTF
    generation feeds off DWARF DIEs, and as such, CTF records of kind
    CTF_K_RESTRICT cease to be generated when DWARF version is 2.
    
    This patch fixes the failure of these testcases on Darwin by using an explicit
    -gdwarf-4 in the dg-options. This keeps the CTF record generation for restrict
    type qualifier tested.
