Subject: tools: use stamp files to allow parallel build of autogen files

Autogen seems to output on the creates files gradually, something that
makes 'make' believe that the command is complete prior to the output
file being fully populated. The current approach uses stamp files to
ensure that no incomplete files are used for compilation.
