Modified files:
	.              : WHATS_NEW make.tmpl.in 
	lib            : Makefile.in 

Log message:
	Create a symlink, e.g., libdevmapper.so.1.02, in the build dir,
	alongside the .so file.  This helps build dynamically linked LVM.
	
	* lib/Makefile.in (VERSIONED_SHLIB): Define.
	* make.tmpl.in (TARGETS): Append $(VERSIONED_SHLIB).
	($(VERSIONED_SHLIB)): New rule.
