initial target tracing support and reporting
The purpose is being able to examine particular target interdependency graph for a given image having been configured to avoid convoluted dependencies (loops in particular). The implementation is based on SHELL hook hint by John Graham-Cumming: http://cmcrossroads.com/ask-mr-make/6535-tracing-rule-execution-in-gnu-make
