[build system] cannot build static library for any windows-gnu target

[codehz]

The build.zig

const Builder = @import("std").build.Builder;

pub fn build(b: *Builder) void {
    const target = b.standardTargetOptions(.{});
    const mode = b.standardReleaseOptions();
    const lib = b.addStaticLibrary("demo", "src/main.zig");
    lib.setTarget(target);
    lib.setBuildMode(mode);
    lib.install();

    var main_tests = b.addTest("src/main.zig");
    main_tests.setBuildMode(mode);

    const test_step = b.step("test", "Run library tests");
    test_step.dependOn(&main_tests.step);
}

command:

D:\Temp\demo> zig build -Dtarget=x86_64-windows-gnu
error: FileNotFound

some details:
it seems try to copy libdemo.a but there only demo.lib in cache folder.
crash in

zig/lib/std/build.zig

Line 2415 in 0e2d858

try builder.updateFile(self.artifact.getOutputPath(), full_dest_path);

and got zig build ... --name demo ... here

zig/lib/std/build.zig

Lines 2102 to 2103 in 0e2d858

	zig_args.append("--name") catch unreachable;
	zig_args.append(self.name) catch unreachable;

Seems like a duplicate of #6483
