Ok I got it working,
All I had to do is compile with lame enabled like this:
./configure --enable-libmp3lame
make
sudo make install
Now everything is back to normal except that lame does not really encode to
my selected sample rate. Something that I will live with for now, hoping it
will be fixed in the future:
avconv -i iTunes_test1_AAC-LC_v4_Stereo_VBR_128kbps_44100Hz.m4a -ar 44100
-ab 40000 -ac 2 -acodec libmp3lame 44100.mp3
avconv -i iTunes_test1_AAC-LC_v4_Stereo_VBR_128kbps_44100Hz.m4a -ar 22050
-ab 40000 -ac 2 -acodec libmp3lame 22050.mp3

As you can see only a few bytes different.
