I discussed this with Mark (cc-ed) it seems to be a problem with linker when dealing with compressed debug info data, which is enabled in your .config
it works for me when I disable CONFIG_DEBUG_INFO_COMPRESSED option
Mark will fix this upstream, meanwhile he suggested workaround we can do in resolve_btfids tool, that I'll try to send shortly
thanks, jirka
