Tests fail when `_interpreters` extension is disabled

Bug report

Bug description:

My CPython version: 3.14.4 (problem with 3.14.3 too)

Configure:
./configure --disable-shared --enable-optimizations --without-lto

Select modules:

./Modules/makesetup -c ./Modules/config.c.in -s ./Modules ./Setup.my.local
mv config.c ./Modules/

File (github says *.local file upload is not expected, change ext txt -> local)
Setup.my.txt
As you can see, the _interpreters module is disabled

And make:
make -j4

Error after testing:

...
File ".../Lib/test/datetimetester.py", line 7304, in test_concurrent_initialization_subinterpreter
...
Traceback (most recent call last):
  File "<string>", line 2, in <module>
    from concurrent.futures import InterpreterPoolExecutor
ImportError: cannot import name 'InterpreterPoolExecutor' from 'concurrent.futures'
...
Ran 1098 tests in 10.101s

FAILED (failures=1, skipped=53)
test test_datetime failed
make: *** [Makefile:990: profile-run-stamp] Error 2

I think a test with a non-existent module should be skipped, not crashed
Also, why does a test failure cause the build to fail if these tests are just needed to collect statistics?

CPython versions tested on:

3.14

Operating systems tested on:

Linux

Lib/test/datetimetester.py の test_concurrent_initialization_subinterpreter 周辺から始め、concurrent.futures.InterpreterPoolExecutor が _interpreters 拡張にどのように依存しているかを調べます。_interpreters を無効にして影響を受けるテストを実行し、その後、利用できない機能が意図したとおりに処理され、プロファイル実行のテストコマンドがこの失敗なしで完了することを確認します。
