 If one has `Coin-or` installed (and a self compiled version of Sage) then
 a doctest fails in the linear programming tutorial
 {{{
 sage -t linear_programming.rst
 **********************************************************************
 File "linear_programming.rst", line 432, in
 doc.en.thematic_tutorials.linear_programming
 Failed example:
     p.solve()  # rel tol 2e-12
 Expected:
     2.0
 Got:
     2.0000000000040004
 Tolerance exceeded:
     2.0 vs 2.0000000000040004, tolerance 2e-12 > 2e-12
 **********************************************************************
 }}}
 We just increase the tolerance to `2e-11`.
