This is fine.

I have a question though.

Akim> +    local ($traces) = "$ENV{amtraces} ";

Do we really want to use an environment variable?  Eventually automake
will default to using the autoconf trace facility.  At that time I
suppose we'll generate a rule in that looks like:

    $(AUTOMAKE) --autoconf=$(AUTOCONF) ...

... and the default will be to use `autoconf'.
Why not just go ahead and implement that now, with the caveat that
tracing is only enabled if --autoconf is given?

(And for now we wouldn't document --autoconf in automake --help or in
the manual.)
