#!/bin/sh
# The NDK's clang, as the linker rustc runs for an Android target.
#
# The buck-side twin of this is toolchains/ndk.sh, which the C toolchain gets
# as a dependency; both resolve the same archive, pinned in one place —
# android-ndk.dotslash beside this script. rustc reaches it through a shim
# instead because -Clinker takes a plain string: rustc_flags cannot carry an
# artifact path, so the linker has to be something with a stable name. The cfg
# in toolchains/BUCK is what keeps two NDKs from sharing a cache entry.
#
# ANDROID_NDK_HOME wins if it is set, so a machine that already has an NDK
# skips the download.
