That's just because, unlike the Cygnus configure one, autoconf's
$(program_transform_name) doesn't start with a -e.  In fact, autoconf
uses `;' as the sed command separator, whereas Cygnus configure used
to use multiple sed commands, each one prefixed by -e.  autoconf's
approach is reportedly a little bit more portable.

This unfortunately means that your fix is not quite perfect yet, since
multiple transform commands would be word-split and sed might take
them as input file names.  I suggest replacing:

        t='$(program_transform_name)'; echo as | sed -e $$t ; \

with

        echo as | sed '$(program_transform_name)'; \

that is the construct used by automake.
