Which toolchain to cross-compile for RPi3

Mark81

I cannot find a working toolchain to cross-compile Qt5.6 for RPi3 in a Debian environment.
Here the official ones:

but they don't recognize the flags in qmake.conf of linux-rpi3-g++ mkspec.
Which toochain should we use? I need to build all modules.

You can follow this wiki article:

Use the linux-rasp-pi2-g++ device as it works on RPi3 as well.

@olejl77 this is the article I'm actually following! But the gcc-linaro-arm-linux-gnueabihf-raspbian doens't support ICU:

and I don't understand which compiler the Qt5 stuff had in mind when wrote the linux-rpi3-g++ mkspec file because the architecture and the compiler flags are not supported!
