How to use the m5ops in gem5 such m5_exit and m5_dump_stats in se mode - gem5

Question

I know this a trivial question but I am having difficulties in running the m5ops in gem5,
lets take for example the m5-exit.c file that has been provided by gem5, in the test programs, how would I compile it and link it to the file m5op_x86.S
Currently this is the way I am compiling and linking it:
gcc m5-exit.c -I ~/Desktop/gem5_86/gem5/include -o test ~/Desktop/gem5_86/gem5/util/m5/m5op_x86.S
the error i get:
/tmp/ccXsGX3d.o: relocation R_X86_64_16 against undefined symbol `M5OP_ARM' can not be used when making a PIE object; recompile with -fPIC
the directory i am in is:
gem5/tests/test-progs/m5-exit/src
the code for m5-exit.c is from the gem5 directory found here

Answer 1

This is a copy of: How to use m5 in gem5-20 which was deleted on my other answer, since my previous DRY link-only answer was removed followed by an unsuccessful (although correct, but not enough users who care) dupe close attempt.
On gem5 046645a4db646ec30cc36b0f5433114e8777dc44 I can do:
scons -C util/m5 build/x86/out/m5
gcc -static -I include -o main.out main.c util/m5/build/x86/out/libm5.a
with:
main.c
#include <gem5/m5ops.h>
int main(void) {
m5_exit(0);
}
Or for ARM:
sudo apt install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu
scons -C util/m5 build/aarch64/out/m5
aarch64-linux-gnu-gcc -static -I include -o main.out main.c \
util/m5/build/aarch64/out/libm5.a
But in practice, I often just don't have the patience for this business, so I just misbehave and add raw assembly directly as shown here muahahaha e.g.:
#if defined(__x86_64__)
#define LKMC_M5OPS_CHECKPOINT __asm__ __volatile__ (".word 0x040F; .word 0x0043;" : : "D" (0), "S" (0) :)
#define LKMC_M5OPS_DUMPSTATS __asm__ __volatile__ (".word 0x040F; .word 0x0041;" : : "D" (0), "S" (0) :)
#elif defined(__aarch64__)
#define LKMC_M5OPS_CHECKPOINT __asm__ __volatile__ ("mov x0, 0; mov x1, 0; .inst 0xFF000110 | (0x43 << 16);" : : : "x0", "x1")
#define LKMC_M5OPS_DUMPSTATS __asm__ __volatile__ ("mov x0, 0; mov x1, 0; .inst 0xFF000110 | (0x41 << 16);" : : : "x0", "x1")
