Delete a dummy ChangeLog in ‘make distclean’.
‘make distcheck’ from git may create a dummy ChangeLog file in the
build directory. Delete this on ‘make distclean’, but don’t delete
a real ChangeLog (generated by the gen-ChangeLog rule).
* Makefile.am (distclean-local): Delete ChangeLog if it is the dummy
created to pacify automake.
