Thanks again for this! I slightly modified it for the blog post, which you can 
see in draft form at <https://issues.guix.gnu.org/60112>. I used 'gcc:lib' 
instead of 'libgccjit' as it is smaller, and changed the needed display options 
to be like the previous ones I had. Yours didn't work for me since it looks 
like it relies on sharing something from GDM, which I don't use. But do let me 
know if my version doesn't work for you.

Also gave you credit for this example; if you prefer not to be mentioned by 
name/link to the mailing list for any reason, just let me know.

Oh, and we do have some (older) patches for building the Tor Browser from 
source, but I don't know if they currently work: 
<https://issues.guix.gnu.org/42380> Your example was great though, something 
very useful!
