Incorrect installation of `lib-dynload` for custom builds on openSUSE

Bug report

Bug description:

from Python-3.13.2.tar.xz

./configure --prefix=$RUN/python/3.13.2
make -j 16
make -j 4 install

dynamic libraries are installed to $RUN/3.13.2/lib64/python3.13/lib-dynload
but internally sys.path uses $RUN/3.13.2/lib/python3.13/lib-dynload

setting a link resolves the

errors that show up:

Reproduisez la compilation personnalisée à l’aide des commandes ./configure, make et make install indiquées sous Linux, puis examinez en quoi le chemin lib-dynload installé diffère de sys.path. La correction est terminée lorsque des modules d’extension tels que _opcode et _posixsubprocess sont trouvés sans lien symbolique et que pip peut s’exécuter correctement.
