JFYI, This issue is caused by CONFIG_DEBUG_INFO now being default off in 
my .config from commit f9b3cd245784 ("Kconfig.debug: make DEBUG_INFO 
selectable from a choice").

By enabling that config faddr2line now looks ok again.

BTW, Could we add a check for any kernel dependency in this tool?

Thanks,
John
