// `-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.
// This test simply checks that this flag can be passed alongside verbatim syntax
// in rustc flags without a compilation failure or the removal of expected symbols.
// See https://github.com/rust-lang/rust/pull/100101
