I was dealing with the same issue, and this is what helped me out:

The trick to getting dlltool.exe is to install MSYS2 as indicated in the Rustup book Windows docs. However there are additional steps involved, which the documentation doesn't spell out. Additionally other MSYS2 libraries need to be installed to get the AWS SDK for Rust to build.

1. Download and install MSYS2, e.g. to C:\msys64.
2. Important: Go into the MSYS2 terminal and install the following packages to get libtool.exe and others

pacman -S --needed base-devel mingw-w64-ucrt-x86_64-toolchain \  
    mingw-w64-ucrt-x86_64-nasm

3. Add C:\msys64\ucrt64\bin to your PATH. (Don't forget to restart your terminal or otherwise update the current environment to pick up the change.)

Without installing mingw-w64-ucrt-x86_64-toolchain, the AWS SDK for Rust will fail to find dlltool.exe as described above. Without mingw-w64-ucrt-x86_64-nasm, AWK SDK for Rust cannot compile its new crypto library.

Visual Studio Code's Using GCC with MinGW instructions are helpful.
