 assemble: don't let a missing runtime dir abort replace_toolchain_libs 
Each NDK has only one of lib64/clang and lib/clang, so ls exits 2 for the
other pattern. Under pipefail that status survived head and set -e
killed the script without a message, right after the bin/ loop.

Android NDK Custom

Android NDK Custom is a custom-built Android NDK that replaces the default toolchain with a rebuilt LLVM and related binaries.

It integrates alternative libc implementations like musl (via Zig), Bionic (from the official Android NDK), llvm-mingw and the macOS SDK (via osxcross) to provide a more flexible and portable build environment.

This project is inspired by Zongou’s build system.

🚀 Features

  • Custom LLVM build sourced from official Google repositories.
  • Built using various toolchain's libc.
  • Additional Tools Built:
    • Shaderc
    • Python
    • Make
    • Yasm
