This was the PKGBUILD I used, and I updated just before building, because it needed to install clang and llvm. It built using clang, I think it is possible to build with gcc as an alternative but that is what it did by default. I was just building on my regular OpenRC install on my Dell E7470, not in a clean chroot, which has a 4th generation I7 CPU, a low power consumption type so only 4 threads available as this is a lightweight portable laptop. I built on the HDD not in /tmp and RAM, after building I only have about 16GB free space on the partition, there was less than 64GB even adding free HDD space when I started, swap and RAM together.
I forgot I'd done this, but before the second attempt I downgraded rust to rust-1 1.71.0-1-x86_64.pkg.tar.zst from the Artix archive, as this predates the problem versions and my first try failed during a rustc bit. My /etc/makepkg.conf is unmodified.
The other slightly non-standard thing was just making clean copies for comparison and further attempts without redownloading.
