libfabric is failing to build on 32-bit architectures. The failure is
blocking migration to testing, and will therefore block mpich migration.

e.g. armhf https://buildd.debian.org/status/fetch.php?pkg=libfabric&arch=armhf&ver=2.0.0-4&stamp=1742062166&raw=0

This might be a gcc-15 error, which tightened type checking.

Upstream has released v2.1.0 with gcc-15 fixes, though I don't know
if it fixes this 32-bit build error.
