No, it shouldn't. That is the deprecated way of configuring this and the
one shown below is correct:

The issue here is that wpa_supplicant was built without support for
control interface (CONFIG_CTRL_IFACE=unix in .config) and because of
that, the ctrl_interface parameter is not supported.

You will need to add control interface support into the build, i.e.,
into .config and rebuild (make clean; make) wpa_supplicant.
