On a Pi 4 running the *32 bit default Raspbian* I get - 
#define __ARM_SIZEOF_WCHAR_T 4
#define __ARM_FEATURE_SAT 1
#define __ARM_ARCH_ISA_ARM 1
#define __ARMEL__ 1
#define __ARM_FEATURE_UNALIGNED 1
#define __ARM_FP 12
#define __ARM_SIZEOF_MINIMAL_ENUM 4
#define __ARM_PCS_VFP 1
#define __ARM_FEATURE_LDREX 4
#define __ARM_FEATURE_QBIT 1
#define __ARM_ARCH_6__ 1
#define __ARM_32BIT_STATE 1
#define __ARM_FEATURE_CLZ 1
#define __ARM_ARCH_ISA_THUMB 1
#define __ARM_ARCH 6
#define __arm__ 1
#define __ARM_FEATURE_SIMD32 1
#define __ARM_FEATURE_COPROC 15
#define __ARM_EABI__ 1
#define __ARM_FEATURE_DSP 1

On a Pi 4 running *64 bit Gentoo* I get - 
#define __ARM_SIZEOF_WCHAR_T 4
#define __ARM_FEATURE_IDIV 1
#define __ARM_FP 14
#define __ARM_SIZEOF_MINIMAL_ENUM 4
#define __ARM_FEATURE_FMA 1
#define __ARM_ALIGN_MAX_PWR 28
#define __ARM_FP16_FORMAT_IEEE 1
#define __ARM_FP16_ARGS 1
#define __ARM_FEATURE_CLZ 1
#define __ARM_64BIT_STATE 1
#define __ARM_ARCH_PROFILE 65
#define __ARM_PCS_AAPCS64 1
#define __ARM_ARCH 8
#define __ARM_FEATURE_UNALIGNED 1
#define __ARM_ARCH_8A 1
#define __ARM_NEON 1
#define __ARM_ALIGN_MAX_STACK_PWR 16
#define __ARM_FEATURE_NUMERIC_MAXMIN 1
#define __ARM_ARCH_ISA_A64 1

This same Gentoo reports
mprotect(x,y,PROT_READ | PROT_EXEC): Permission denied
when I try to run the 64 bit ARM VM.

I could have sworn I had a uSD with Raspbian64 on it but it seems not. I'll make one and test on that again.
