Multimedia configure fails for targets with no opengl

Multimedia configure step fails for non-opengl target (possibly since commit "Enable DMA buffer support for gstreamer" https://codereview.qt-project.org/c/qt/qtmultimedia/+/362787)

One Boot2Qt CI target (Colibri-imx6ULL) is such a target and fails with error:

Make Error at /home/qt/work/build/build/tmp/work/cortexa7t2hf-neon-mx6ul-poky-linux-gnueabi/qtmultimedia/6.2.0-r0/recipe-sysroot/usr/lib/cmake/Qt6Core/Qt6CoreMacros.cmake:2063 (add_library):
Target "Multimedia" links to target "EGL::EGL" but the target was not found.
