I was about to apply this, but unfortunately, it breaks the build with
rpi-userland as the egl provider:

/home/test/outputs/qt5/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/include/interface/vcos/vcos_types.h:38:33: fatal error: vcos_platform_types.h: No such file or directory
 #include "vcos_platform_types.h"

I checked, and without your patches, the build works fine. The
defconfig I'm testing is:

BR2_arm=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-arm-full-2015.05-496-g85945aa.tar.bz2"
BR2_TOOLCHAIN_EXTERNAL_HEADERS_4_1=y
BR2_TOOLCHAIN_EXTERNAL_LOCALE=y
# BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_DEBUG is not set
BR2_TOOLCHAIN_EXTERNAL_INET_RPC=y
BR2_TOOLCHAIN_EXTERNAL_CXX=y
BR2_PACKAGE_QT5=y
BR2_PACKAGE_QT5BASE_LICENSE_APPROVED=y
BR2_PACKAGE_QT5BASE_EGLFS=y
BR2_PACKAGE_QT5BASE_JPEG=y
BR2_PACKAGE_QT5BASE_PNG=y
BR2_PACKAGE_QT5DECLARATIVE=y
BR2_PACKAGE_QT5MULTIMEDIA=y
BR2_PACKAGE_QT5QUICK1=y
BR2_PACKAGE_QT5SENSORS=y
BR2_PACKAGE_QT5SERIALPORT=y
BR2_PACKAGE_QT5SVG=y
BR2_PACKAGE_QJSON=y
BR2_PACKAGE_QUAZIP=y
BR2_PACKAGE_RPI_USERLAND=y

Maybe Bernd or Yann can help with this Raspberry Pi specific issue?

It's clearly a header path missing. It's probably caused by the
refactoring of how the platform-specific EGL stuff is handled in Qt5.
