Configure: error: cannot guess build type; you must specify one

Hi all, i have just received my Khadas VIM 1 Pro and i am trying to turn it into a seedbox with rTorrent and ruTorrent following this guide:

However, i am stuck trying to compile, it gives me the error that is shown in the title.

The line of instructions i am sending throught the terminal is this one:

./configure --disable-libwww-client --disable-wininet-client --disable-abyss-server --disable-cgi-server

Trying to install this:

Install XML-RPC

I have tried to solve it typing “$./configure --build=aarch64”, i have downloaded the updated scripts, but i dont know what to do with them, i searched on Google a lot, but i am still stuck in this step.

Can you help me please on how to solve this ?
