I'm currently involved in a project which uses Guix to build a number of
cross-compiling toolchains, with Guix time-machine. On a recent update of
the time-machine, one cross-toolchain (powerpc64-linux-gnu) was no-longer
building, failing with:

Adding powerpc64-linux as a platform resolves this issue.
I'm wondering if there's any reason this cannot, or wouldn't be added as a
platform definition?

I changed ‘system’ to #f, since it’s not supported in Guix, and tweaked
the commit log.

Thanks!
