This depends on the used CPU, but on x86, the smallest binary I can
build without modifying the code is 81 kB (PSK only, debugging
disabled). valgrind memory profiling (massif) shows about 8 kB memory
use for WPA2-PSK. If there were large number of APs in scan results,
more memory would be used, but in general, the memory use is pretty
minimal for PSK case.
