Add makefile debugging rule for printing out the value of a variable.
From http://blog.melski.net/tag/debugging-makefiles/.
Example:
[13:14:59] johnny:/Volumes/data/lldb/svn/trunk/test/class_static $ make print-CC
CC=gcc
origin = file
flavor = recursive
value = gcc
[13:15:09] johnny:/Volumes/data/lldb/svn/trunk/test/class_static $ make print-LD
LD= g++
origin = file
flavor = recursive
value = $(call cxx_linker,$(CC))
[13:15:21] johnny:/Volumes/data/lldb/svn/trunk/test/class_static $ make print-CXX
CXX= g++
origin = file
flavor = recursive
value = $(call cxx_compiler,$(CC))
