There should not be an X11 dependency for Flutter Engine Linux embedder build. I want to implement my own shell, and not have X11 dependency.

gclient sync --revision flutter-1.18-candidate.5 -j 8

./flutter/tools/gn --runtime-mode debug --embedder-for-target --full-dart-sdk --enable-fontconfig --target-os linux --linux-cpu arm --arm-float-abi hard --target-triple arm-linux-gnueabihf --target-sysroot /media/joel/SolidState/rpi/rpi0w/tmp/work/arm1176jzfshf-vfp-poky-linux-gnueabi/flutter-engine/git-r0/recipe-sysroot --target-toolchain /media/joel/SolidState/LLVM8.0

Command: python /media/joel/SolidState/engine/src/build/config/linux/pkg-config.py -s /media/joel/SolidState/rpi/rpi0w/tmp/work/arm1176jzfshf-vfp-poky-linux-gnueabi/flutter-engine/git-r0/recipe-sysroot -a arm --system_libdir lib x11

I think if --embedder-for-target is passed, no shell should be included.
