Notes for updating external/libffi from source

Note: AOSP has (or had) a platform/external/libffi used by Dalvik/MIPS. To avoid confusion, we call our version of the library libffi-cheets.

Files added for use in cheets:

• ./Android.mk
• ./MODULE_LICENSE_BSD_LIKE
• ./NOTICE (copy of ./LICENSE)
• ./README.cheets.md
• ./linux-arm/ffi.h
• ./linux-arm/fficonfig.h
• ./linux-arm/ffitarget.h
• ./linux-x86/ffi.h
• ./linux-x86/fficonfig.h
• ./linux-x86/ffitarget.h

The ffi.h, fficonfig.h, and ffitarget.h files allow us to easily configure each build target.

Note that Android.mk embeds the version of Wayland being built (ends up in src/wayland-version.h)

Files generated by the build process

These files are generated by the Android.mk makefile into the source directory, and should not be checked in.
