Hello,

In addition to the problem with static guile in Hurd, the static binary `xz`
shows the following message when trying to check the version. 


--8<---------------cut here---------------start------------->8---
jin@Hurd:~/glibc-2.28/bin$ ./xz --version
./xz: Error creating a pipe: Function not implemented
--8<---------------cut here---------------end--------------->8---

The binarie was generated from current Guix (master branch) in Linux,
with `./pre-inst-env guix build bootstrap-tarballs --target=i586-pc-gnu`.

I attach the rpctrace.
