I would try upgrading qttest first (it is the one pulling
qtcore-5.9.6{,-r1}, according to the output). Do you have any qttest
5.11.* version which is keyworded amd64 (and not ~amd64)?

Here and on https://packages.gentoo.org/packages/dev-qt/qttest,
qttest-5.11.1 is amd64. Maybe the tree was in an inconsistent state when
you last synced it?

If you have qttest 5.11.1 in ~amd64 and you need a very quick fix, try
adding it to package.accept_keywords and upgrading it. Otherwise, you
might prefer to sync the portage tree again first.
