bug#71383: Guile 3.0.9 / error missing auxiliary stack implementation for architecture

Dear Guile devs,

I've got a build time error, related to my specific architecture "e2k-mcst-linux-gnu" (i believe):

--- snip ---
Making all in libguile

I will be glad, if possible to fix this issue.
For that I am also attaching you a full config.log for details.


Thanks.
