During the recent staging cycle, I noticed a huge number of SBCL build
failures, especially when emulating aarch64 on x86_64.

If it was an emulated build, that's more or less expected. The emulation
is very slow.

Comparing the Overdrive 1000 (4 x Cortex-A57, 25 watts TDP) to the
Odroid N2 (4 x Cortex-A73 and 2 x Cortex-A53, only 5 watts TDP), I'd
guess the Overdrive will complete the compilation more quickly, despite
the older design and lower core count.

I'm retrying the build now on one of the Overdrives.
