Three initial bits about Guix's support for mips64el:
1. We stopped producing a standalone installer for mips64el before the
1.0 release, which means it's been years since anyone has been able to
install it without help. Actually, 0.12 was the last version¹, back in
2016.
2. We supported the Lemote Fuloong 2F²/Loongson 2 (MIPS III) processors.
Except for very specific sticks of RAM, it only supported 1GB of RAM. As
for the processor, I believe most other distributions moved to the
Loongson 3 as their base. Debian³ 9 (in 2017) it seems switched to
Loongson 3A/3B based machines for their Loongson support.
3. "Generic" --target=mips64el-linux-gnu support from the GNU toolchain
doesn't support Loongson 2 chips, it needs some extra flags. I tested
this a few years ago and wasn't able to run a cross-compiled package on
one of our decommissioned mips64el build machines (citation needed).

I suggest that we stop cross-compiling packages to mips64el since it is
really dead-dead, and not just mostly-dead or nearly-dead.
