config/optimize: add -gdwarf-4 for split debug info builds

Browse Source 
Since gcc 11 -gsplit-dwarf no longer implicitly enables -g and needs
a separate -g option. For some yet unknown reasons the default DWARF 5
format doesn't work, gdb doesn't show debug info, but DWARF 4 works fine
so use that.
