Hello Guix users / package maintainers,
I updated guix today using `guix pull && guix package -u`, but even before
that, I had an issue starting a Racket REPL simply entering `racket`:

Not sure what is up, or whether it is only on my end for some reason.
Also cannot call `racket --version`:
~~~~
$ racket --version
Segmentation fault (core dumped)

I was able to run 'guix shell racket -- racket --version' with it
segfaulting. Same thing when I switched to using the same commit that
you're using.
Can you paste the output of 'lscpu'? I suspect that there might be some
optimizations being applied during build time and it's been optimized
with features not available in your CPU.
