[BUG] Cannot re-compile hello world aarch64 binary

[M4ndUwU]

Describe the bug
When I run the instrumentation pass, the link step fails with undefined references to the AFL runtime symbols:

/usr/lib/gcc-cross/aarch64-linux-gnu/11/../../../../aarch64-linux-gnu/bin/ld: /tmp/ccEu0nM0.o: in function `myarea':
(.afl_sec+0x3): undefined reference to `__afl_area_ptr'
/usr/lib/gcc-cross/aarch64-linux-gnu/11/../../../../aarch64-linux-gnu/bin/ld: /tmp/ccEu0nM0.o: in function `myprev_loc':
(.afl_sec+0xb): undefined reference to `__afl_prev_loc'
collect2: error: ld returned 1 exit status

Describe how to reproduce the bug

1. Platform: ARM64 (aarch64)
2. Compiler: aarch64-linux-gnu-g++ (GCC 11), targeting aarch64 Android coverage.
3. Code: a minimal test binary (test_bin)
4. OS / Environment: Ubuntu 20.04 x64

Recompilation

# 1) generate an Android-coverage-instrumented .s
./retrowrite -m android_coverage test_bin test_bin.s   # succeeds

# 2) apply the analysis pass
./retrowrite -a test_bin.s test_bin_inst              # fails with undefined reference errors
