bug#32339: Nix import

[Andreas Enge]

This bug is resolved by following the current documentation and
executing
   export NIX_REMOTE=daemon
.

However, even then the import fails:

$ guix import nix nixpkgs/ hello

;;; SSAX warning: Skipping PI: xml

trace: warning: `stdenv.isArm` is deprecated after 18.03. Please use 
`stdenv.isAarch32` instead
trace: lib.zip is deprecated, use lib.zipAttrsWith instead
trace: Warning: `showVal` is deprecated and will be removed in the next 
release, please use `traceSeqN`
trace: `mkStrict' is obsolete; use `mkOverride 0' instead.
trace: `lib.nixpkgsVersion` is deprecated, use `lib.version` instead!


And after about 15 minutes the import crashes with a stack overflow.
