// Setting the linker flavor as a C compiler should cause the output of the -l flags to be
// prefixed by -Wl, except when a flag is requested to be verbatim. A bare linker (ld) should
// never cause prefixes to appear in the output. This test checks this ruleset twice, once with
// explicit flags and then with those flags passed inside the rust source code.
// See https://github.com/rust-lang/rust/pull/118202
//@ only-linux
// Reason: the `gnu-cc` linker is only available on linux
