Comment:

 I added my working branch to the ticket.
 I could not find if and where I should store the tarballs of the new spkg?

 As of today (sept 28 2015); they correspond to the upstream version of the
 3 libs: givaro, fflas-ffpack and linbox.

 I added .pc files for givaro and fflas-ffpack (coming soon for linbox),
 and defined the extra_compile_flages in `modules_list.py` as suggested by
 fbissey.

 This is still work in progress:
  * !LinBox sparse solver make the test-suite fail: I'm investigating the
 problem, which I could not reproduce in !LinBox for the moment.
  * the extra_compile_flags should be inferred from the .pc files (harcoded
 for the moment). I did not find how to use pkg-config through python to do
 it.
