Related issues: #123748, #130366, #129043
Problem:
In Python 3.14.0a5, when compiling on macOS Silicon without specifying the --enable-universalsdk parameter (as there is no need to compile a universal version for x86_64 & arm64), an error "unknown type name 'Lib_IntVector_Intrinsics_vec256'" occurs.
Compilation parameters:
./configure --prefix=/Applications/ServBay/package/python/3.14/3.14.0a5 --enable-ipv6 --enable-loadable-sqlite-extensions --with-openssl=/Applications/ServBay/package/common/openssl/3.2 --enable-optimizations --with-system-expat --with-system-libmpdec --with-readline=editline --with-lto --enable-framework=/Applications/ServBay/package/python/3.14/3.14.0a5Problem analysis:
The Python team previously released a patch for this issue, but in the configure and configure.ac scripts, the patch uses the $UNIVERSAL_ARCHS parameter for condition checks. This fix does not completely resolve the issue because $UNIVERSAL_ARCHS depends on the --enable-universalsdk parameter being passed. Without this parameter, the initial value of $UNIVERSAL_ARCHS is UNIVERSAL_ARCHS="32-bit", leading to the condition if test "$UNIVERSAL_ARCHS" != "universal2"; then not being effective.

// blablablaRepair solution:
In the configure and configure.ac scripts, it is necessary to use other conditions for checks instead of relying on $UNIVERSAL_ARCHS.
Attached is a quick fix patch based on build_cpu and build_vendor. However, this is not the most appropriate solution.
