Those instructions use wpa_supplicant/defconfig more or less as-is as
the build configuration which is not really ideal for the case where
only eapol_test is built. This leaves some unneeded build parameters
like various driver interfaces enabled. That is not really needed for
eapol_test and it would be easier to simply disable those.

For libnl version 3 to work, you would need to uncomment
CONFIG_LIBNL32=y in wpa_supplicant/.config. That said, it will be
simpler to just comment out (or just delete the lines)
CONFIG_DRIVER_WEXT=y and CONFIG_DRIVER_NL80211=y in
wpa_supplicant/.config when building only eapol_test and not
wpa_supplicant. That will remove dependency on libnl completely.
