The failure is because that PR (python/cpython#122566) changes the CI to use the latest devcontainer. We did actually not switch to that yet (see python/cpython#125571), so you get at least two failures:

• check generated files will fail since there is a mismatch between the autoconf devcontainers used by Tools/build/regen-configure.sh and the autoconf devcontainer in the CI
• the WASI check fails because the autoconf-archive patch does not (yet) work out of the box for us: Configure EXEEXT hacks are interfering with AX_C_FLOAT_WORDS_BIGENDIAN cpython#125698

I'm closing this, since this is already tracked in the following issues:

• Configure EXEEXT hacks are interfering with AX_C_FLOAT_WORDS_BIGENDIAN cpython#125698
• Patch autoconf-archive with an updated variant of AX_C_FLOAT_WORDS_BIGENDIAN #22
