Since LLVM 13, llvm-dlltool can imply the target architecture from a triple prefix on the tool name, so there's no more need for a wrapper. The *-dlltool tools are now symlinks to the main llvm-dlltool executable. In the Windows distribution, the *-dlltool.exe used to be copies of dlltool-wrapper.exe (which is small; 15 KB). Now they will instead be copies of llvm-dlltool.exe. Luckily, thanks to building with -DLLVM_LINK_LLVM_DYLIB=ON by default, llvm-dlltool.exe is only a mere 65 KB, while it used to be much larger, e.g. around 11 MB in older releases.
