Hi guix,

Overview:
  (%build-inputs --> inputs, native-inputs)
  #1: gnu: ci: Use 'inputs' in build phases instead of '%build-inputs'.
  #2: gnu: smalltalk: Use 'inputs' in phases instead of '%build-inputs'.
  #3: gnu: neovim: Use 'inputs' in phases instead of '%build-inputs'.
  #4: gnu: qemacs: Use 'native-inputs' instead of '%build-inputs'.
  #5: gnu: ding: Use 'inputs' in build phases instead of '%build-inputs'.

  (more smalltalk fixes)
  #6: gnu: smalltalk: Move 'zip' from 'inputs' to 'native-inputs'.
  #7: gnu: smalltalk: Find glibc even when cross-compiling.

See patch descriptions for details.

This would cause 5 rebuilds:
  ./pre-inst-env guix refresh --list-dependents ding qemacs neovim smalltalk cuirass
  No dependents other than themselves: cuirass@1.0.0-17.31fd4d4 smalltalk@3.2.91 neovim@0.4.4 qemacs@0.3.3 ding@1.8.1

Building succeeds:

  ./pre-inst-env guix build ding qemacs neovim smalltalk cuirass

Cross-compilation: somewhat improved

  # ding: ok, refers to binaries of correct architecture
  # qemacs: cannot cross-compile, because its dependency libxv
  #  tries to run a test program (even when cross-compiling)
  #  (during configuration, "checking whether malloc(0) returns NULL...")
  # neovim: cannot cross-compile, because its dependency "libtermkey" is not cross-compilable
  # cuirass: the meson build system does not support cross-compilaion
  # smalltalk: still some failures, even after patches (#6 and #7)
  #
  #  ./gst --no-user-files --kernel-dir "./kernel" --image gst.im -iQ /dev/null
  #  ./gst: line 117: /tmp/guix-build-smalltalk-3.2.91.drv-0/smalltalk-3.2.91/.libs/gst: cannot execute binary file: Exec format error
  #  ./gst: line 117: /tmp/guix-build-smalltalk-3.2.91.drv-0/smalltalk-3.2.91/.libs/gst: Success
  ./pre-inst-env guix build ding --target=aarch64-linux-gnu

Greetings,
Maxime.
