Hmm. On thinking about it, the output:

# cpu-x
CPU-X:core.c:301: failed to call libcpuid (CPUID instruction is not supported)
CPU-X:core.c:1478: failed to find chipset vendor and model
CPU-X:core.c:1480: failed to find graphic card vendor and model
CPU-X:core.c:2260: failed to retrieve CPU temperature (fallback mode)

that also occured may be more of an indication that aarch64 is not
actually supported by the infrastructure used. The Makefile should
possibly block doing aarch64 builds that will not work. Likely more
than aarch64 would have that status.

I'll also note: headless, so no "graphic card vendor and model" to
find.
