Related to #39016.
Meson has an option to select different vscrt, but rustc always uses msvcrt.lib. To work around that issue, Meson adds -l static=msvcrtd.lib when we need use debug crt. This seems to work fine, unless a rust test program is built with rustc --test. In that case I get that linker issue:
[2/6] "rustc" "-C" "linker=link" "--color=always" "-C" "debug-assertions=yes" "-C" "overflow-checks=no" "--crate-type" "bin" "-C" "link-arg=/release" "-C" "link-arg=/nologo" "-g" "--crate-name" "rust_test_from_static" "--emit" "dep-info=rust_test_from_static.d" "--emit" "link=rust_test_from_static.exe" "--out-dir" "rust_test_from_static.exe.p" "--test" "-l" "static=msvcrtd" "../test cases/rust/9 unit tests/test.rs"

Any idea what causes that? Any workaround possible?
