Failed to run "build_android.sh" i686-linux-android-g++: error: unrecognized command line option '-fno-limit-debug-info'

Issue description

I want to compile all the android native libraries (.a & .so) to x86 processor.
While running the "build_android.sh" script i'm getting failed error regarding the make file.

Code example

I tried running both for x86 and arm64, failed to do so in both scenarios:

./scripts/build_android.sh -DANDROID_ABI=arm64-v8a -DANDROID_TOOLCHAIN=clang
./scripts/build_android.sh -DANDROID_ABI=x86 -DANDROID_TOOLCHAIN=clang

System Info

Mac 10.12.6
Android NDK - R14
cmake version 3.12.0
clang Apple LLVM version 9.0.0 (clang-900.0.39.2)
Target: x86_64-apple-darwin16.7.0

The error while running the build with x86 is :

is not able to compile a simple test program.

It fails with the following output:
