Did you mean to write something different in your last sentence?  It 
IS the same thing as objects placed beside source files, unless I
misunderstand what you mean by "beside".

This makefile will always write the object files into the same
directory as the source files.  As long as you want to do that, then
you can use suffix rules or pattern rules very easily.

It's when you want object files to go into a different directory from
source files that suffix rules won't work well (you can use VPATH to
help somewhat).
