    Makefile.am: Fix NEWS and ChangeLog generation under vpath builds
    
    Make sure NEWS generation uses top_srcdir to allow "make release-news" to
    work under a vpath build (directory outside the source tree).
    Update ChangeLog target to use $(top_srcdir)/missing. This fixes a problem
    where running "make dist" under a vpath build directory would include an
    empty ChangeLog.
