Log Message:
patches/patch-doc_api_Makefile_am
  Remove. The patch was to remove unnecessary (unwanted)
  man pages for the build directories including ${WRKSRC}
  generated by doxygen.
  Equivalent for-loop was gone in doc/api/Makefile.am now.
  The logic is now in post-install: target in (pkgsrc) Makefile.

  This removal was meant in previous commit and distinfo does not
  include this removing patch. Sorry for left out patch itself.
  Thanks dholland@  pointing out.
