# Since cargo 1.31, install only uses $CARGO_HOME/config, ignoring $PWD.
#   https://github.com/rust-lang/cargo/issues/6397
# But we can set CARGO_HOME locally, which is a good idea anyway to make sure
# it never writes to ~/.cargo during rpmbuild.
# We also need RUSTC_BOOTSTRAP since we use -Z avoid-dev-deps
# until it gets stabilized: https://github.com/rust-lang/cargo/issues/5133
