That's just a guess but to me this makes a lot of sense. It may happen
that your source files have to be compiled several times, e.g. with
different compiler options, in order to produce different targets. My
intuition is that it is to avoid collisions between potential multiple
compilations of the same source file that automake is generating such a
Makefile.

hth,
