I think the issue is that xhurd-headers must have --host=3Di686-pc-gnu in
its configure flags.

You say that in that case ./configure fails with =E2=80=9Cgcc cannot produce
executables=E2=80=9D.  Could you send xhurd-headers=E2=80=99 config.log for=
 that case?

Some additional comments:

> +(define-public glibc/hurd=20
> +  (package (inherit glibc)

This definition basically copies all of the =E2=80=98glibc=E2=80=99 definit=
ion.  This is
fine for now, but eventually this will need to be factorized.

Also, ideally, we=E2=80=99d like to hide the fact that there are two differ=
ent
glibcs.  So I imagine that we would:

  1. Rename =E2=80=98glibc=E2=80=99 to =E2=80=98glibc/linux=E2=80=99.

  2. Have =E2=80=98glibc/hurd=E2=80=99 inherit from it, just replacing =E2=
=80=98source=E2=80=99,
     =E2=80=98propagated-inputs=E2=80=99, =E2=80=98inputs=E2=80=99, and add=
ing the pre-configure phase
     that unpacks libpthread.

  3. Define =E2=80=98glibc=E2=80=99 as a magic macro that chooses between =
=E2=80=98glibc/linux=E2=80=99
     and =E2=80=98glibc/hurd=E2=80=99 depending on the current system/targe=
t (see
     =E2=80=98pkg-config=E2=80=99 for an example.)

In parallel, we=E2=80=99ll have to lobby so our Hurd friends publish tarbal=
ls of
glibc and libpthread.

> +                    #:optional (xbinutils (cross-binutils target)) libc)

Likewise, we shouldn=E2=80=99t need a Hurd-specific variant here.

HTH,
