circular dependency

[Stepan Kasal]

Hello,
  while building hal, my version of make (GNU Make 3.81) reports
circular dependency because of the rule
	ChangeLog: $(srcdir)/ChangeLog

With builddir = srcdir, this is the same file.

I recognize that we need a rule for "ChangeLog" to silence Automake.

Would not the following simplification be sufficient?

Thanks,
	Stepan Kasal
