  When I regtested this, I used the official Ubuntu 20.04 package of
automake 1.15. When generating the Makefile.in, I do see a few entries
that I did not expect, so therfore I would like someone with the right
versions to generate the Makefile.in and submit this for me.

The alternative approach to this patch is to figure out what functions
(in addition to __ssputws_r) that is also needed in nano formatted io.

Regression tested in basepoints/gcc-14-9032-g945cb8490cb with arm-none-eabi.

Example failure without this change:

In case you need different Autotools releases often, building your own Autotools set is not hard, and I have written a script which automatically downloads and builds the desired versions:
