I'd suggest porting over the autotools approach (via a temporary file)
or even moving the hunk to Makefile.gen (or Makefile.common) and using
it in both builds.

Related: wondering about moving the includes/cflags - although with
the aosp build changes, things might be problematic. Do you foresee
(from Android POV) any issues with doing that ?

Thanks
