(svn r1180) Makefile: fixed dependancies so the flag -j can be used. It makes the compilation process into more than one job which makes it able to benefit from multiple CPUs. Using -j without setting a limit of jobs (like -j2) is not a great idea (thanks to ln-- for reporting the need for this one)
