[GStreamer (GNOME Bugzilla)]

--- Comment #8 from Justin J. Kim <justin.joy.9to5 at gmail.com> ---
I tried to build from clone again to be sure what I was doing correctly.
If I use `-I<NDK path>/sysroot/usr/include` (not <NDK
path>/platforms/android-xx/), cebero fails to build in iconv, gnutls.

iconv.

```

It seems to be caused because NDK headers have different definitions than usual
headers. For Android N, FSETLOCKING should be disabled in gettext.

But, still I wonder what is 'libintl-stub'?
