Does it still happen with modern golang?
I just re-emerged dev-go/blackfriday-1.4::gentoo under current dev-lang/go-1.8.1::gentoo I did not get the same error. Then I upgraded to dev-lang/go-1.8.3::gentoo and again re-emerged dev-go/blackfriday-1.4::gentoo and I did not trigger the error message either. I wonder if this was maybe fixed by https://gitweb.gentoo.org/dev/heroxbd.git/commit/?id=ccaf4051612bbff71447bdcdb9a9b888bffbbbbc . I think was I involved in some thread triggered via Gentoo:Prefix or Gentoo::RAP for which heroxbd@g.o made a patch related to automatic scanelf execution "as needed". But I am not sure this is the actual change.
