// `-Z packed_bundled_libs` is an unstable rustc flag that makes the compiler
// only require a native library and no supplementary object files to compile.
// Output files compiled with this flag should still contain all expected symbols -
// that is what this test checks.
// See https://github.com/rust-lang/rust/pull/100101
//@ ignore-cross-compile
// Reason: cross-compilation fails to export native symbols
