That is not possible with current Autoconf and Libtool.  Sorry.
You can only choose that at configure run time, not at autoconf
run time.  But that makes sense: configure run time is the earliest
time when the system in question is nailed down.  And it is system-
dependent which shell is appropriate to use.

(As we cannot know whether your 'autogen' script runs configure
or not, we cannot know whether that is a problem for you or not.)

There should be no problem with dash.

But it does.  Not autoconf; but configure does try to find a decent
shell unless you set CONFIG_SHELL when invoking configure.

IIUC then that means you haven't tried it yet, right?

Please try 2.2.6 before complaining further about its execution time;
we do not have the resources to support non-fatal bugs in old versions
of Libtool; and slower execution time is a non-fatal bug.
