Great news! I think using only 1 core fixes it. But since --cores=1 is
broken for cross-compilation it seems, I had to use a single-core VM.

Can you do the same? (Create a single-core x86_64 however you want VM,
run a command and report hashes)

$ guix gc && sha256sum "$(guix build -M 1 -c 1 --target=powerpc64le-linux-gnu -e '(@@ (gnu packages make-bootstrap) %gcc-bootstrap-tarball)')/gcc-stripped-5.5.0-powerpc64le-linux-gnu.tar.xz"

Also try with powerpc64-linux-gnu:

$ guix gc && sha256sum "$(guix build -M 1 -c 1 --target=powerpc64-linux-gnu -e '(@@ (gnu packages make-bootstrap) %gcc-bootstrap-tarball)')/gcc-stripped-5.5.0-powerpc64-linux-gnu.tar.xz"

Thanks a lot!
