Migration to `0.12.0` from `0.11.0` causes linker errors

[gh0st-work]

Zig Version

0.12.0 (x86_64-unknown-linux-gnu)

Steps to Reproduce and Observed Behavior

Basically I have Rust -> C -> Zig interop, that is built via bash script:

#!/bin/bash

set -xeo pipefail
args="$@"
rust_re=deps/rust/re
rust_target=x86_64-unknown-linux-gnu
cwd=$(pwd)

cd $rust_re
rustup +nightly component add rust-src
cargo +nightly build --release -Zbuild-std-features=panic_immediate_abort --target $rust_target 
cd $cwd
zig test -lc -L$rust_re/target/$rust_target/release -lre -I$rust_re $args

-Zbuild-std-features=panic_immediate_abort flag on rustc/cargo means do not unwind on panic, just abort
On version 0.11.0 it compiles and runs successfully. On version 0.12.0 it spits:

I can compile it linking with libunwind or c++, but it will be great to known what is the issue, why it suddenly stopped working. Last time it worked because it was a fluke and you somehow just changed the internals?

Expected Behavior

Compile / know what's changed

[kassane]

Maybe missing, -lunwind (EH ABI) or try replacing -lc to -lc++. Also, for zig triple-target arch-linux-gnu, remove unknown

Also, most likely need to change the label from bug to question
