I've just build qt for android, and i have QtSerialPort and
QtSerialBus, now just need to test it on target.
My understanding is that these 2 modules are buildable for Android,
but are not provided by default due to the 'app developer' use case as
explained by Denis.

A stock Android NDK has the kernel headers for CAN, but doesn't have
libsocketcan.
libsocketcan doesn't seem to be necessary, as per configure's output
----
Qt SerialBus:
  Socket CAN ............................. yes
  Socket CAN FD .......................... yes
----
This was on the 5.12 git branch.

And looking at the source code, it seems QtSerialPort authors took the
right decision to use low level Linux API only. Thanks for that!
