OK.

2.I installed Audacity by Packages Manager and if I open the help window into Audacity, it gives this information: Audacity 1.3.12.beta (unicode).
Then that version won't recognise git FFmpeg.

I don't know how to check with Ubuntu if they have modified Audacity to disable amr in their version.

I read in Audacity Preferences that the FFmpeg library used is: F(52.64.2),C(52.72.2),U(50.15.1)
Then you are loading the pre-installed FFmpeg library that comes with Ubuntu, not the FFmpeg git version you compiled. If you browse for the git version, Audacity won't load it because it needs to be recompiled with the
changes I mentioned.

3.I don't understand what you mean for "to compile SVN HEAD of Audacity". SVN and HEAD are acronyms of which words?
SVN = the
subversion version control system. HEAD means the latest trunk development code. "HEAD" would mean the same as "SVN HEAD" assuming there is not another trunk under another version control system (there isn't).

Do you know a possible way to solve the problem avoiding a new installation of Audacity?
As it is now, either the 1.3.12 Ubuntu package of Audacity has amr export disabled, or the FFmpeg library they built (F(52.64.2),C(52.72.2),U(50.15.1)) has amr disabled. To use the git FFmpeg that has amr enabled so as to give you an AMR menu choice in the Audacity export window, you have to compile the latest HEAD code of Audacity using the
steps I gave you.
Alternatively, export as WAV from the Audacity 1.3.12 you have now, then convert the WAV to AMR at the command line using git FFmpeg.
You could also try sending a command to git FFmpeg using the
Audacity command line encoder. I am not sure if that would work with git FFmpeg or not, but it might as it avoids the FFmpeg library checking and loading from Preferences that is done if you use the export items for WMA, AC3 and so on. There is no way to import files supported by FFmpeg into Audacity without loading the FFmpeg libraries via Preferences.
