#!/bin/sh
# zig, as the C toolchain, out of the tarball buck fetched.
#
# The buck-side twin of scripts/zcc, and the same argument rewriting: cc-rs
# builds a `--target=` from the Rust triple, which carries a vendor field —
# `x86_64-unknown-linux-gnu`. zig's own triples have no vendor, and it refuses
# the whole query rather than ignoring the part it does not want, reporting
# "unable to parse target query: UnknownOperatingSystem" as though Linux were
# the problem.
#
# $1 is the directory the tarball unpacked into and $2 the zig subcommand — cc,
# c++, ar or ranlib. buck passes both; nothing here can work them out.
