Thank you for making LibAFL better!

Describe the bug When following the build instruction in README.md in libfuzzer_libpng, the following error occurred when compiling libpng with libafl:

libtool: link: gcc -dynamiclib  -o .libs/libpng16.16.dylib  .libs/png.o .libs/pngerror.o .libs/pngget.o .libs/pngmem.o .libs/pngpread.o .libs/pngread.o .libs/pngrio.o .libs/pngrtran.o .libs/pngrutil.o .libs/pngset.o .libs/pngtrans.o .libs/pngwio.o .libs/pngwrite.o .libs/pngwtran.o .libs/pngwutil.o arm/.libs/arm_init.o arm/.libs/filter_neon.o arm/.libs/filter_neon_intrinsics.o arm/.libs/palette_neon_intrinsics.o mips/.libs/mips_init.o mips/.libs/filter_msa_intrinsics.o powerpc/.libs/powerpc_init.o powerpc/.libs/filter_vsx_intrinsics.o   -lz  -g -O2   -install_name  /usr/local/lib/libpng16.16.dylib -compatibility_version 54 -current_version 54.0 -Wl,-single_module -Wl,-exported_symbols_list,.libs/libpng16-symbols.expsym
Undefined symbols for architecture arm64:
  "___sanitizer_cov_trace_pc_guard", referenced from:
      _png_set_sig_bytes in png.o

      _png_reset_crc in png.o
      _png_calculate_crc in png.o
      _png_user_version_check in png.o
      ...

However, when I run cargo make run, the problem solves itself. My assumption is that in the README file, it configures libpng with ./configure, while in Makefile.toml, the library is configured by ./configure --enable-shared=no --with-pic=yes --enable-hardware-optimizations=yes. It would be good if the developers can confirm the configuration in the makefile is correct and correct the corresponding part in the README file. Thanks!

To Reproduce Platform: MacOS Arch: ARM64 (M1 Pro)

Build the libfuzzer_libpng following instruction in the README file.
