 Our workaround we currently use to cope with issues cross-compiling rustc
 for 32bit Windows us not upstreamable (see: https://github.com/rust-
 lang/rust/pull/55444 for the arguments). We could think about compiling
 with a mingw-w64 using dwarf exception support instead, see:
 (https://github.com/rust-embedded/cross/blob/master/docker/mingw.sh).

 However, we should take into account that we want to switch to a mingw-w64
 /clang-based toolchain soon and should start looking into this ticket not
 before the other (#28238) is done.
