title: Makefile(s) debug: which file/line calls to a command?
body: <p>I'm facing a bug in a makefile build system (Android built under Linux) - some files are removed by an 'rm' command, and I can see that command in the build log.</p>
  
  <p>How can I find the exact line in the makefiles which calls the 'rm' ? Is there any automated method?</p>
