Ensure that `static_crt` is set in the bootstrapper whenever using `cc-rs` to get a compiler command line. When attempting to build rustc with LLVM on Windows, I noticed that the CRT flag provided to the C and C++ Compilers was inconsistent: ``` "-DCMAKE_C_FLAGS=-nologo -MT -Brepro" "-DCMAKE_CXX_FLAGS=-nologo -MD -Brepro" ``` Since the bootstrapper also sets the various `LLVM_USE_CRT` variables, this resulted in cl.exe reporting a bunch of warnings: ``` cl : Command line warning D9025 : overriding '/MD' with '/MT' ``` The root cause for this is that `cc_detect::find` was creating a `cc::Build` twice, but didn't set `static_crt` the second time. It's possible that this what is also causing #81381 |
