    tools/dwarves: update to v1.27
    
    Update to the latest upstream version and add a patch that enables pahole
    reproducible builds if SOURCE_DATE_EPOCH is defined in the environment.
    
    This patch helps avoid BTF-related module loading problems with packages
    built separately from the kernel such as mac80211 or kselftests-bpf, e.g.:
