Linking error when building with target-feature=+crt-static

This feature makes Visual C++ runtime to be linked output binaries statically.
I found a workaround but maybe there is some better way?

I build on Windows with:
MS Visual Studio 2019
Vulkan SDK 1.2.162.1
rustc 1.48.0 (7eac88abb 2020-11-16)

Code (build.rs):
```rust
use anyhow::*;
use glob::glob;
use std::path::PathBuf;

struct ShaderData {
src: String,
src_path: PathBuf,
spv_path: PathBuf,
kind: shaderc::ShaderKind,
}

impl ShaderData {
pub fn load(src_path: PathBuf) -> Result {
let extension = src_path
.extension()
.context("File has no extension")?
.to_str()
.context("Extension cannot be converted to &str")?;
let kind = match extension {
"vert" => shaderc::ShaderKind::Vertex,
"frag" => shaderc::ShaderKind::Fragment,
"comp" => shaderc::ShaderKind::Compute,
_ => bail!("Unsupported shader: {}", src_path.display()),
};

let src = std::fs::read_to_string(src_path.clone())?;
let spv_path = src_path.with_extension(format!("{}.spv", extension));

Ok(Self {
src,
src_path,
spv_path,
kind,
})
}
}

fn main() -> Result<()> {
// Collect all shaders recursively within /src/
let mut shader_paths = [
glob("./src/**/*.vert")?,
glob("./src/**/*.frag")?,
glob("./src/**/*.comp")?,
];

let shaders: Result> = shader_paths
.iter_mut()
.flatten()
.map(|glob_res| -> Result { ShaderData::load(glob_res?) })
.collect();
let shaders = shaders?;
let mut compiler = shaderc::Compiler::new().context("Unable to create shader compiler")?;

for shader in shaders {
println!(
"cargo:rerun-if-changed={}",
shader
.src_path
.as_os_str()
.to_str()
.expect("Failed to get string name for shader")
);
let compiled = compiler.compile_into_spirv(
&shader.src,
shader.kind,
shader.src_path.to_str().unwrap(),
"main",
None,
)?;
std::fs::write(shader.spv_path, compiled.as_binary_u8())?;
}
Ok(())
}
```

Cargo.toml:
```
[build-dependencies]
anyhow = "1.0"
glob = "0.3"
shaderc = "0.7"
```

I run build in Powershell with commands:
```powershell
$env:RUSTFLAGS="-C target-feature=+crt-static"
cargo build
```

I expect build to compile but got this (this is only a part, a lot of omitted):

I currently use a hack with specifying target explicitely. It makes cargo send custom compiler flags only to the final binary compilations and ignore build scripts:
```
cargo run --target x86_64-pc-windows-msvc
```

Start with the build.rs and Cargo.toml example, then reproduce the Windows MSVC build using RUSTFLAGS="-C target-feature=+crt-static" and cargo build. Inspect how the shaderc build dependency is linked when the static CRT is enabled. Done means the build succeeds without requiring an explicit target workaround.
