Note that the shown line is a warning only, but from your attached log:

	arm-buildroot-linux-gnueabihf-g++.br_real: fatal error: Killed signal terminated program cc1plus
	compilation terminated.

Most likely out-of-memory? Install more ram/swap on your build machines or
reduce the amount of parallelism of your (qt5webengine-5.15.2) build,
e.g. via setting BR2_JLEVEL or by hacking the following line in
package/qt5/qt5webengine/qt5webengine.mk:

 62 QT5WEBENGINE_ENV += NINJAFLAGS="-j$(PARALLEL_JOBS)"

Peter
