missing "bootstrap" sh files for `emar`, `emranlib`, `emcmake` and many others

**Version of emscripten/emsdk:**
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 4.0.21 (d6f42310010ddec0753a6
9bab01a4b33aae255b7)
clang version 22.0.0git (https:/github.com/llvm/llvm-project 60513b8d6ebacde46e8fbe4faf1319ac87e990e
3)
Target: wasm32-unknown-emscripten
Thread model: posix
InstalledDir: C:\emsdk\upstream\bin

**Failing command line in full:**
`bash: emar: command not found`

**Full link command and output with `-v` appended:**
```shell
make generic CC='emcc' AR='emar rcu' RANLIB='emranlib' MYLDFLAGS="-sALLOW_MEMORY_GROWTH -sWASM_BIGINT -sENVIRONMENT=web"
```

~~After updating emscripten, sh files for emar and emranlib are missing or not created in **%EMSDK%**\upstream\emscripten. i can not use in mingw64.~~
~~As workarround i created copies of `bootstrap` file and then remaned to emar and emranlib.~~

~~Also noticied that **maint** directory is missing in **%EMSDK%**\upstream\emscripten\tools.~~

~~I always follow the update instructions from [https://emscripten.org/docs/getting_started/downloads.html](https://emscripten.org/docs/getting_started/downloads.html)~~

EDIT: **lastest working version was 4.0.12**, newer versions do not include these files:
- emar
- embuilder
- emcmake
- emmake
- emnm
- emprofile
- emranlib
- emrun
- emscan-deps
- emscons
