This looks very much like the tar segfault I encountered when I last
played with the Hurd port.

My notes say this:

--8<---------------cut here---------------start------------->8---
- tar fails to run when building gnu-make-boot0
./pre-inst-env  guix build -e '(@@ (gnu packages commencement) gnu-make-boot0))'
here’s the error:
building /gnu/store/ybi3cyxqwm55gvwn9i1nczg2ns5ha34q-make-4.2.1.tar.xz.drv...

This works:
/gnu/store/dqlhjyvg0n8v1kdvwfpliqy46n7kpjqb-bootstrap-binaries-0/bin/tar cvfa 
hello.tar.xz /tmp

But it segfaults with “--mtime=@0”

Quite likely!

How would that help?  Or is it just a guess that a later GCC would be
better here?

On the “core-updates” branch we are using a later GCC already.
