- Update config files.
    - Refresh patches.suse/stack-unwind.
    
    Reenable dwarf stack unwinder for C. Assembler is not dwarf-friendly
    annotated (removed in upstream and neither
    patches.arch/x86_64-unwind-annotations is enabled (yet)), so dwarf
    unwinder does not work there (yet).
    
    This should be fixed by Josh Poimbeouf's stacktool later. But until
    then, dwarf-unwind at least C and use frame pointers for asm.
    
    I.e. no more question marks for most cases:

    Leftover inexact backtrace:
