How to Perform GNU Make Files Analysis

Question

We have many GNU Make files. I would like to use every target used during build to identify performance bottlenecks. Is there a tool or technique to do this in a convenient and automatic way?

I would like to analyze these results in order to monitor the performance factor, since changes in assembly and growth (but they are already quite large and complex).
