It didn’t. mrustc builds, but when rust’s build phase tries to use it,
mrustc errors out:

There’s an unmerged PR for mrustc adding support for ppc64 but I haven’t
tried it:

https://github.com/thepowersgang/mrustc/pull/159[1]

Accessing the link now, I see that someone reported being able to bootstrap
rustc 1.29 on powerpc64le-linux with it!  \o/

I’ll try it out within the next couple of days and send a patch if it works.

And duktape builds on ppc64le. :-)

Changing subjects a bit: I forgot to report in my last email that I tested:

$ guix pull --url=$HOME/src/guix \
	--branch= core-updates-frozen-batched-changes

on powerpc64le-linux and it worked. Well, almost. It did when I included
the mariadb patch from https://issues.guix.gnu.org/51376[2] (which is already
in core-updates-frozen).
