In solve_l2r_lr_dual, the if-condition "newton_iter < l/10" is replaced by "newton_iter <= l/10." Otherwise, the inner epsilon may never be changed for l < 10.

Fix clean build on 64-bit platform by removing dependency on ../linear.o. By adding
this, ../linear.o is built without proper CFLAGS (say -fPIC) as it is built by
current Makefile instead of ../Makefile. Without this dependency, the cost is
everytime we type 'make', it relinks so again (should be fine though).
