manylinux_2_28 armv7l cross python not detecting piwheel wheels

[ReimundR]

Hi, none of the wheels on https://www.piwheels.org/ are detected by the cross python pip.

Example: https://www.piwheels.org/project/cffi/

How to reproduce:

python3.11 -m pip install -U pip
python3.11 -m pip install crossenv
mkdir /opt/cross_env
cd /opt/cross_env && python3.11 -m crossenv --cc $TARGET_CC --cxx $TARGET_CXX --sysroot $TARGET_SYSROOT --env LIBRARY_PATH= --manylinux manylinux_2_28 /opt/python/cp311-cp311/bin/python3 py3.11
ln -s /opt/cross_env/py3.11/bin/cross-python /bin/cross-python3.11
cross-python3.11 -m pip config set global.extra-index-url https://www.piwheels.org/simple
cross-python3.11 -m pip install cffi

Output:

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Collecting cffi
  Downloading cffi-2.0.0.tar.gz (523 kB)

Although this file is available:
https://www.piwheels.org/simple/cffi/cffi-2.0.0-cp311-cp311-linux_armv7l.whl

Any suggestions what is going wrong?

I see now, the same is for standard https://pypi.org/ for aarch64.
