The Ubuntu guides do not (and probably will not ever) supply
instructions to build libvo_aacenc. It provides rather poor quality
compared to the available alternatives, and some even consider it worse
than the native FFmpeg AAC encoder. There are better alternatives
available that ffmpeg supports; especially since you compiled ffmpeg and
can choose any supported encoder.

If you still want to use libvo_aacenc, then install the libvo-aacenc-dev
package, or compile it from source, and then add the
"--enable-libvo-aacenc --enable-version3" ffmpeg configure options.

libfaac (also libfdk-aac and libaacplus, IIRC) require --enable-nonfree
which results in a non-redistributable build, so the static builds will
not support these encoders.

See the FFmpeg and AAC Encoding Guide for more info and examples:
