Problems compiling libmad-0.15.1b on ARM CortexA9

HI all,
I am trying to compile libmad-0.15.1b on Wandboard with Freescale's
i.MX6 Solo processor (ARM Cortex-A9) running Ubuntu Precise LTS.

First I had to comment out "-fforce-mem" from configure, as suggested here :
http://mpd.wikia.com/wiki/TomTom

Then I have error of this kind :
/tmp/cczQx5fc.s: Assembler messages:
