I agree, but for the moment being I'm just interested in ensuring the
removal of the 'cygnus' option won't impact too negatively on its last
relevant users (GCC, GDB, Binutils, and the bfd library).  So far it
appears this is the case luckily, so I'll go ahead with the deprecation
of 'cygnus' in Automake 1.12.1 and its removal in Automake 1.13.
