I've now repaired these ommissions; that being said, I opted to
recommend modifications to the Makefiles different from those you
mentioned, for include paths are customarily exported through the
variable LOCAL_EXPROT_C_INCLUDE_DIRS, not variables meant for exporting
CFLAGS.

Hello,

Duaring building Emacs Android port, I encountered some modules that could
not build without specifying system include header file by -isystem.

These modules are

libxml2:
add LOCAL_EXPORT_CFLAGS := -isystem $(LOCAL_PATH)/include
 to its Android.mk.

lbjansson:
add LOCAL_EXPORT_CFLAGS := -isystem $(LOCAL_PATH)/src -I
$(LOCAL_PATH)/android
 to its Android.mk

core/libpackagelistparser:
add LOCAL_EXPORT_CFLAGS := -isystem $(LOCAL_PATH)/../include
(I installed it from core/libpackagelistparser)

Thanks,
