This fails for me too if sys-devel/bison is >=3.7. With bison-3.6.4, dev-qt/qtwebkit builds fine. There is a tracker for things broken by bison-3.7: https://bugs.gentoo.org/737026 I believe this bug should be added there, but I do not think I have the necessary bugzilla privs to make that change myself.
Thank you to Hans Leininger, I discovered that sys-devel/bison-3.7 is installed on my gentoo system (I do not know by what it has been installed). I downgraded sys-devel/bison from 3.7 to 3.6.4 and I could compile successfully dev-qt/qtwekbit. This is fine. I think that dev-qt/qtwebit has to be added to the list of things broken by sys-devel/bison-3.7. The problem is solved for me.
Please do not change the status of this bug again. *** This bug has been marked as a duplicate of bug 736499 ***
