autogen.sh: Prefere automake 1.11 over other releases

Browse Source 
GNU automake 1.11 is the last release supporting "de-ANSI-fication"
using the included ansi2knr tool. And becuase we _want_ to support old
K&R platforms, we try hard to use this release of automake when
available to generate our build system.
