Bug#1020054: h5py: FTBFS: ld: final link failed: bad value

[Drew Parsons]

Source: h5py
Version: 3.7.0-2
Followup-For: Bug #1020054

Reproducible, e.g.
https://tests.reproducible-builds.org/debian/rbuild/unstable/amd64/h5py_3.7.0-2.rbuild.log.gz

I suspect the bug is not in h5py but rather in libhdf5-openmpi-dev,
possibly in the flags used by h5pcc.

The last hdf5 version is 1.10.8+repack-1, but h5py previously built
fine against it. Not clear at this point why the behaviour has
changed. Perhaps the switch from gcc-11 to gcc-12 is involved.
