Updating the QEMU patches
When updating to the latest American Fuzzy Lop, make sure to check for any new patches to qemu for binary fuzzing support:
https://github.com/mirrorer/afl/tree/master/qemu_mode
Be sure to check the build script and make sure it's also using the
right QEMU version and options in qemu.nix:
https://github.com/mirrorer/afl/blob/master/qemu_mode/build_qemu_support.sh
afl-config.h and afl-qemu-cpu-inl.h are part of the afl source
code, and copied from config.h and afl-qemu-cpu-inl.h
appropriately. The QEMU patches need to be slightly adjusted to
#include these files (the patches try to otherwise include files
like ../../config.h which causes the build to fail). See qemu.nix
for details.
