To avoid all doubt, could you please copy and paste the output of the
appended shell script on an iOS device?

For reference, this is what it prints on the GCC Compile Farm's arm64
OSX machine:

uname -m = "arm64"
uname -p = "arm"
uname -r = "20.3.0"
uname -s = "Darwin"
uname -v = "Darwin Kernel Version 20.3.0: Thu Jan 21 00:06:51 PST
2021; root:xnu-7195.81.3~1/RELEASE_ARM64_T8101"

Thanks,

#! /bin/sh
UNAME_MACHINE=$( (uname -m) 2>/dev/null) || UNAME_MACHINE=unknown
UNAME_PROCESSOR=$( (uname -p) 2>/dev/null) || UNAME_PROCESSOR=unknown
UNAME_RELEASE=$( (uname -r) 2>/dev/null) || UNAME_RELEASE=unknown
UNAME_SYSTEM=$( (uname -s) 2>/dev/null) || UNAME_SYSTEM=unknown

printf 'uname -m = "%s"\n' "$UNAME_MACHINE"
printf 'uname -p = "%s"\n' "$UNAME_PROCESSOR"
printf 'uname -r = "%s"\n' "$UNAME_RELEASE"
printf 'uname -s = "%s"\n' "$UNAME_SYSTEM"
