ndk-patches: Patch to 'define MB_CUR_MAX 4'

The platform headers has the following macro:

  #define MB_CUR_MAX __ctype_get_mb_cur_max()

where __ctype_get_mb_cur_max() tries to handle UTF-8 encodings.

However, even in Android 7.0 setlocale(LC_ALL, ""), which many
programs do at startup, doesn't work in that it sets the locale
as non-utf8:

  https://android.googlesource.com/platform/bionic/+/nougat-release/libc/bionic/locale.cpp#139

So we just always consider us being in an utf-8 locale.

Also rebuild coreutils to fix #1136.
