[build-tested using this defconfig:
BR2_x86_64=y
BR2_TOOLCHAIN_BUILDROOT_GLIBC=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_PACKAGE_KODI=y
BR2_PACKAGE_MESA3D=y
BR2_PACKAGE_MESA3D_DRI_DRIVER_I965=y
BR2_PACKAGE_MESA3D_OPENGL_EGL=y
BR2_PACKAGE_XORG7=y
BR2_PACKAGE_PYTHON=y
BR2_PACKAGE_PYTHON_PY_ONLY=y]

Kodi still builds using an uClibc-toolchain. Please send the patch 
upstream.
