Hah! You beat me to the punch, I have/had similar patch sitting in my
own repo that I was going to submit this week.

Builds and runs fine on my setup, so:

Tested-by: Andrey Smirnov <andrew.smirnov at gmail.com>

NOTE: I did notice that my original patch that added zstd has a bug
where it install tools to "/usr/local/bin" instead of "/usr/bin". I'll
submit a patch to fix that shortly.

Thanks,
Andrey Smirnov.
