[Comment 8 PaX Team 2021-09-02 09:17:11 UTC]

the problem seems to be that if dev-util/abi-dumper is installed, xen-tools will detect its presence and enable its use however it fails to also enable -g or similar in CFLAGS which is required for the necessary debug information to be present.

a quick workaround is to unmerge or rename abi-dumper while emerging xen-tools (adding -g in make.conf's CFLAGS doesn't seem to get passed down to its build system, another problem for another day :).

last but not least, bugs 791463 and 803581 seem to be related to this problem as well.

Thanks for pointing this out, we'll remove the abi-dumper call and it'll fix the 2 other bugs you mentioned.
