minor corrections

[Ilya Zakharevich <ilya@math.ohio-state.edu>]

a) CVS.txt says:

    cvs -d :pserver:cvs@megrez.math.u-bordeaux.fr:/home/megrez/cvsroot login

  Hit return when asked for a password (there's no password); then back to
  the shell prompt

    cvs -z3 -d :pserver:cvs@megrez.math.u-bordeaux.fr:/home/megrez/cvsroot checkout pari

In fact on the second line -d serv... is not needed.

b) Oarchitecture/Makefile does not list gp-sta gp-dyn as dependencies
   for dobench.  Thus

     make -j4 bench

   runs things in a wrong order.
