Changing PREFIX to INSTALL_PREFIX to avoid clashing with possibly set environment variables. Adding logic to handle if we are on termux on android (adapted from previous croc install script). Adding an info message for what prefix was set to. Adding in armv71 support (need to add more or make this a generic case to catch more arm devices).
