Compiles fine with USE=-vaapi
I can confirm this problem with USE=vaapi (and that it compiles and installs fine with USE=-vaapi )
The same issue happens with opencv-3.4.1-r1.
Can you please submit build.log and emerge --info?

I see the same error with USE=vaapi
Same with =media-libs/opencv-3.4.1-r4, USE=-vaapi will build. USE=vaapi will not build.
For completeness that's USE="examples vaapi" that fails, USE="-examples vaapi" works. Fixed upstream: https://github.com/opencv/opencv/commit/20f5fa8e3e880bc8b2e5156e9f25f7fb756ed8e4 Applies fine to opencv-3.4.1-r5.
Looking at the ebuild DEPEND seems to miss: vaapi? ( x11-libs/libva ) Appears that libva is used directly, and not just in the examples e.g.: modules/core/src/va_intel.cpp
