# The Android clang toolchains share most of the same parameters, so we have this
# wrapper around gcc_toolchain to avoid duplication of logic.
#
# Parameters:
#  - toolchain_root
#      Path to cpu-specific toolchain within the ndk.
#  - sysroot
#      Sysroot for this architecture.
#  - lib_dir
#      Subdirectory inside of sysroot where libs go.
#  - binary_prefix
#      Prefix of compiler executables.
