Always use Boost compile flag -DNDEBUG.

Without this flag the uBlas Krylov solvers are too slow to be useful. With optimisation, the uBlas BiCGStab solver is about 10% faster than the PETSc BiCGStab solver (no preconditioning in both cases). The uBlas GMRES solver has not been optimised yet, and runs about 2 times slower the the PETSc GMRES solver.
