Hi Pierre,

So ‘libtool’ is not passing ‘-static’, right?  Why is that?  (It does
pick .a libs though.)

I think that’s a reasonable fix for now; you can push the patch.

However, we should eventually switch to GCC 10 in make-bootstrap.scm; I
don’t think there’s any good justification for sticking to GCC 7.

Thank you!
