Hello guix!
After the longest week ever, I'm back. I had to power off my build server
because is a bit noisy, and building llvm on a laptop is slow.

Finally, I upgraded julia to 1.1.1 (even if 1.2 is already at rc2).

I know inline patches are preferred but I don't have access to my email
client right now.

@Ludvic, as you asked, I placed the llvm-patches in an "origin" field, with
2 small helpers functions used to generate the url and the field.

Let me know if this is better, hopefully julia will find its way into guix
:)

Many many thanks, and sorry again for the late response,

Nicolò

Pushed as 7304d5623ab5cc35289cb1535cbd0d8a37691fac!  \o/

I changed a few things to your patch to minimize changes (whitespace
changes, etc.), to avoid tabs, and to build only two LLVM backends.  I
also added a commit log that follows our conventions.

Please take a look and let me know if anything is amiss!

Anyway, it took a loooong time but it successfully built for me on
x86_64-linux.  Thank you!

Ludo’.
