Re: Cross-building bootstrap binaries fail in current master

As discussed on IRC, --target expect a “GNU triplet” such as
“i686-linux-gnu”, so the above thing cannot work.

Note that cross-building from anything to i686 is untested, so it’s not
a good choice.

Regardless, cross-building ‘bootstrap-tarballs’ to one of the supported
target triplets works on master:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix build bootstrap-tarballs --target=mips64el-linux-gnu -n
substitute: updating list of substitutes from 'https://mirror.hydra.gnu.org'... 
100.0%
The following files would be downloaded:
   /gnu/store/lwn9v9jhsllffpc3d4kii8bldw4hfppa-bootstrap-tarballs-0

$ git describe

--8<---------------cut here---------------end--------------->8---

See:

  
https://hydra.gnu.org/job/gnu/master/mips64el-linux-gnu.bootstrap-tarballs-0.x86_64-linux
  
https://hydra.gnu.org/job/gnu/master/mips64el-linux-gnuabi64.bootstrap-tarballs-0.x86_64-linux

So normally, if you pass “--target=powerpc-linux-gnu” (or whichever
triplet is appropriate), that should work too.

HTH!
