    gbuild: work around GDB 10 bug with DWARF5 in split debug info
    
    GCC 11 defaults to -gdwarf-5 and GDB can only read it if
    -gsplit-dwarf isn't used.
    
    Dwarf Error: wrong unit_type in compilation unit header (is DW_UT_split_compile (0x05), should be DW_UT_type (0x02)) [in module /workdir/CObject/desktop/source/app/main.dwo]
