t_pmulti_dset hangs on Fedora Rawhide aarch64 with mpich

[opoplawski]

Describe the bug Trying to build hdf5_1_14 branch in Fedora Rawhide on aarch64. Koji builder seems to hang with:

make[4]: Leaving directory '/builddir/build/BUILD/hdf5-hdf5_1_14/mpich/testpar'
make[4]: Entering directory '/builddir/build/BUILD/hdf5-hdf5_1_14/mpich/testpar'

I'm not seeing this with latest hdf5_1_14 and latest Fedora Rawhide.

I think this may be intermittent. Seen again now with 1.14.5, mpich 4.2.2
