yes: http://autobuild.buildroot.net/?reason=opencv3-3.3.0

Please note that the aarch64 build errors started on June 9th, 2018.

OpenCV 3.4.2 is also affected by the problem, because of that I think 
that patch order does not matter. My first try to fix the build error was 
to bump package version, seeing that this did not fix the problem I 
investigated further and found the VFPV3 problem.

The bug was introduced by https://git.buildroot.net/buildroot/commit/
package/opencv3?id=a17402e42d8c996af239cfdb536e74188d6c6245 on June 7th, 
2018. This patch was only committed to the master branch.
