Bundled with static-link doesn't work on macOS

[Cobrand]

See the latest build status: https://github.com/Rust-SDL2/rust-sdl2/runs/4642055170?check_suite_focus=true

It's coming from #1186 , so probably a bug upstream, or a misconfig on our end

I tried to build it myself, but I also got this warning with the linker:

[...]
ld: warning: object file (/Users/ivanmolinarebolledo/rust-sdl2/target/debug/deps/libsdl2_sys-fd49f5dc146a33ad.rlib(SDL_blendfillrect.c.o)) was built for newer macOS version (11.1) than being linked (10.7)
[...]

This is the full log.

Maybe this is a related issue: widelands/widelands#4679

[RhapsodySiu]

I have similar issue and I'm using Mac M1. The compilation succeeds without "static-link" feature but fails when "static-link" (+"bundled") features are enabled.

extern crate sdl2;

fn main() {
    let _sdl = sdl2::init().unwrap();
}

Only include "static-link" feature

% cargo run
   Compiling sdl2 v0.35.2
   Compiling sdl2-sys v0.35.2
error: could not find native static library `SDL2main`, perhaps an -L flag is missing?

Include both "bundled" & "static-link" features

error: linking with `cc` failed: exit status: 1

I think this and #1241 are related. Not only is the crate not weakly linking CoreHaptics, it seems it's not linking it at all for static builds?

[hikari-no-yume]

I decided to try to fix the CHHaptic issue, but discovered it is already fixed on the current master (0c4fb75)! Somewhere between version 0.35.2 (b36d048) and now, it starts working. I've compiled both versions locally to make sure of it.

I guess this might just be c80f7a4 and 278eda3 but I didn't check.

So all that's needed is a new release.
