Linking to libc for i386-windows-gnu target fails (regression) #12886
Description
Zig Version
0.10.0-dev.4060+61aaef0b0
Steps to Reproduce
On 0.10.0-dev.4060+61aaef0b0 (doesn't happen on 0.10.0-dev.3685+dae7aeb33) I cross-compiled my project on macos, passing -Dtarget=i386-windows-gnu (doesn't happen with -Dtarget=x86_64-windows-gnu) and linked dynamically to SDL2:
exe.addObjectFile(try path.join(b.allocator, &[_][]const u8{base_path, "lib/libSDL2.dll.a"}));
Expected Behavior
For it to compile and link without error
Actual Behavior
zig build -Dtarget=i386-windows-gnu
LLD Link... lld-link: error: <root>: undefined symbol: _tls_index
