Almost there...

Git checkout:
  repository: /home/vince/dev/repo/guix
  branch: bootstrap-ppc64le
  commit: 8159ce1970d91567468cf1bacac313099a009d2a

Only gcc differs, I did not use a channel (nor gc'ed) but just a local
branch at the right commit:

git checkout -b bootstrap-ppc64le 8159ce1970d91567468cf1bacac313099a009d2a
make distclean
./bootstrap
./configure --localstatedir=/var
make -j 16
./pre-inst-env guix build --no-substitutes --target=powerpc64-linux-gnu 
bootstrap-tarballs

PS: Yes, it looks like I misnamed my branch, endian-size-wise...
