[R-pkg-team] Bug#1043532: r-bioc-rhdf5: autopkgtest fails on s390x: 64-bit integer attributes are not read correctly

Dear maintainer(s),

Your package has an autopkgtest, great. However, it fails on s390x (our 
only big endian architecture). Can you please investigate the situation 
and fix it? I copied some of the output at the bottom of this report. I 
strongly suspect the failure is due to endianess, but I'm not sure if 
it's only a test failure, or if the package won't work on big endian 
systems.
