can't build ole32-sys with nightly-gnu

[Eh2406]

HI,

Setup:
Cargo.toml

[package]
name = "test"
version = "0.1.0"
authors = ["Eh2406 <YeomanYaacov@gmail.com>"]

[dependencies]
ole32-sys = "0.2.0"

src/main.rs

extern crate ole32;
fn main() {
    println!("");
}

Expected output:
No errors, as there are no errors when I run cargo +nightly-msvc build

Actual output:

C:\test>cargo +nightly-gnu build
   Compiling winapi v0.2.8
   Compiling winapi-build v0.1.1
   Compiling ole32-sys v0.2.0
error: linking with `gcc` failed: exit code: 3221225781

1.18.0-nightly (0369832 2017-04-26), on windows.

Note: that it works with:

• cargo +nightly-2017-04-20 build
• cargo +nightly-2017-04-24 build
• cargo +nightly-2017-04-25 build

does not work with:

• cargo +nightly-2017-04-26 build

I gonna take a wild guess and say that this is likely related to the LLVM 4.0 upgrade (#40123) or more specifically the switch from MinGW-with-win32-threads to MinGW-with-posix-threads.

@Eh2406: Could you tell us the the MinGW / gcc --version you are using?

(I'm also gonna assume this works on stable)

Looks like this is the same as #31840 (comment) and so should be fixed by #41571.

[Eh2406]

Works with the new nightlies, so guess you got it perfect! Thanks!
