# Compile C++ with zig's bundled glibc sysroot; no system C toolchain
# needed. Same arrangement as vidya's, with one addition it did not need.
#
# `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 —
# "unable to parse target query: UnknownOperatingSystem", which reads as though
# Linux were the problem. aws-lc-sys compiles C, so this is the difference
# between a workspace that builds and one that does not.
#
# Drop the vendor on the way past. Nothing else is touched.
