SDK won't work on Linux Arch

After downloading the SDK from the official website (ArmorySDK-2019-06.zip), i installed the plugin on the system installation of blender, set the SDK path and tried to start blender’s default scene on the browser.

The first changes i had to make were to set some files as executable:

chmod +x ./Armory/Krom/krom
chmod +x ./Armory/nodejs/node-linux64
chmod +x ./Armory/nodejs/copysysbin.sh

Modified and executed the script to rename the nodejs executable

cp "$( dirname "${BASH_SOURCE[0]}" )"/node-linux64 "$( dirname "${BASH_SOURCE[0]}" )"/node

Copied the Kha file make.sh to make (because Armory it doesn’t launch make.sh, but make):

cp Armory/Kha/make.sh Armory/Kha/make

Now if i try to start the scene on the browser directly from the Play button, i get in the system console an error while starting the bash script “make”:
