Modified files:
	.              : configure 

Log message:
	Minor objdir rework to extend flexibility.
	
	the first shot of objdir implementation implied that you did:
	
	cd cluster
	./configure --objdir... etc.
	cd /path/to/objdir
	make
	
	now you can:
	
	mkdir objdir
	cd objdir
	/path/to/configure
	make
	
	NOTE: in this case you don't need to specify objdir. it will be automatically
	set up for you.
	
	As a nice side effect you can also be anywhere on the fs and do:
	
	/path/to/configure --objdir=/path/to/obj
	cd /path/to/obj
	make
	
	and it will work.
