error: link modifiers combination `+bundle,+whole-archive` is unstable when generating rlibs

tested with rust from the fedora repo and from rustup.

So looking at https://doc.rust-lang.org/rustc/command-line-arguments.html#-l-link-the-generated-crate-to-a-native-library +bundle is set by default, so that is likely where that is set.

Then we are normally building to staticlib with the Rust parts, i wonder which part specifically is being built to an rlib and if that's a problem.

This from initial investigation seems to have broken via a newer rustc ?

[ahayzen-kdab]

Manually setting cc_builder_whole_archive.link_lib_modifier("-bundle"); to still allow +whole-archive solves the issue.

But we need to check that

• Is it right that a rlib is being built there?
• Is setting -bundle OK or does that cause other problems?

@Be-ing ^^ any opinions ?

rust-lang/rust#108081 🤔

This is caused by a regression in rustc 1.69: rust-lang/rust#110912

Reopening this until the upstream issue is fixed
