Updated android_ndk_defconfig

busybox now fails to compile with the Android NDK using the provided config
(mostly due to changes in busybox's default options).

FEATURE_TOUCH_NODEREF=n fixes that one.

Next failure:

Adding the patch from #6362 to networking/udhcp/dhcpc.h fixes that.

And finally fails on linking:

MDEV=n, FEATURE_SYNC_FANCY=n, USE_BB_CRYPT=y

Fixes these errors.

Then it dies with "ld: internal error in do_print_to_mapfile, at
/s/ndk-toolchain/src/build/../binutils/binutils-2.25/gold/output.h:395" due to
Google changing it to use gold linker by default.
Fixed by appending -fuse-ld=bfd to CFLAGS

Updated android_ndk_defconfig and patch for udhcpc attached.
