bug#66507: 30.0.50; Cannot build some modules without adding LOCAL_EXPORT_CFLAGS=-isystem ... on Android port.

[ayatakesi <ayanokoji.takesi@gmail.com>]

Hello, again

I tried LOCAL_EXPORT_C_INCLUDE_DIRS, and worked fine
 except core/libpackagelistparser.

When I build libpackagelistparser, make failed with

/home/runner/work/my-emacs/my-emacs/my_sub_modules/core/libpackagelistparser//packagelistparser.c:30:10: fatal error: 'utils/Log.h' file not found
#include <utils/Log.h>
         ^~~~~~~~~~~~~

I cloned core package from Google, and I specify such bellow

directory structure:
core
|-libpackagelistparser
    Android.mk
|-utils
  |-include
      Log.h

in Android.mk:
LOCAL_EXPORT_C_INCLUDE_DIRS += $(LOCAL_PATH)/../include

But LOCAL_EXPORT_C_INCLUDE_DIRS and LOCAL_EXPORT_C_INCLUDES
 did not work except LOCAL_EXPORT_CFLAGS.
