He is most likely using armv7 and that comes with its own issues, ie cpu
type and floating point (hard/soft, neon and simd). aarch64 much easier to
build on.
It looks like he's using aarch64.
You can not tell from that as he could be using a armv7 system and run a
aarch64 kernel, The foundation always run the 64 bit kernel on the 32
bit system. The 32 bit installation script sets the flag in the
config.txt file to run a 64 bit kernel on the 32 bit system on the rpi4.
From /boot/config.txt
# Run in 64-bit mode
arm_64bit=1
