 For compiling for with python 3 support, of course you need to change the links in the CROSSTOOL file, and install the corresponding packets.
 Notice that, since python 3 has different subversions, you need to choose a linux distribution that installs the same packets as the target machine. For example, if you need to install to an Ubuntu 16, you need to create an Ubuntu 16 virtual machine.
