Makefile.am: Add .DELETE_ON_ERROR target.

Browse Source 
* Makefile.am: Add `.DELETE_ON_ERROR` special target; both GNU and
  FreeBSD make(1)s support it so maybe it will be portable enough.  This
  avoids, among other problems, a target appearing falsely up-to-date
  (often as an empty file) when the troff process generating it
  experiences an assertion failure.
