Fixed by these two commits:

  9ee8b41f2b gnu: gnutls: Leave #:disallowed-references empty for GNU/Hurd.
  50e7e6a065 build-system/gnu: Cross builds properly handle #:allowed-references & co.

Hello!

Attempting to cross-build the system to i586-pc-gnu with grafts enabled
leads to something fishy:

The “x86_64-linux” cross-toolchain look very bogus.  It disappears when
adding ‘--no-grafts’.
