Some time ago I set up a Linux host to cross-compile Qt5. I used this configure command:
./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=~/opt/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot ~/opt/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/opt/qt5pi -hostprefix ~/opt/qt5 -v -nomake examples -nomake tests -reduce-exports -no-pch -no-use-gold-linker
and I successfully cross-compiled Qt5.9 with EGLFS support. Now I want update to Qt5.13.
I checked out the git repository and typed the same configure command. Here the configure output:

Cross-toolkit compatibility disabled. WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation. Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation. On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution. On macOS, you can use Homebrew's llvm package. On Windows, you must set LLVM_INSTALL_DIR to the installation path. WARNING: Thumb instruction set is required to build ffmpeg for QtWebEngine. ERROR: Feature 'opengles2' was enabled, but the pre-condition '(config.win32 && !features.opengl-dynamic) || (!config.watchos && !features.opengl-desktop && libs.opengl_es2)' failed. ERROR: The OpenGL functionality tests failed! You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2], QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform. I don't understand why the OpenGL has failed this time. Perhaps I need to install some other libraries? When cross-compiling I always confused if I need to install library for my host on for the target... As side note, it's correct the specified device? I see other people use -device linux-rpi3-vc4-g++.
