The testsuite of HDF5-External-Filter-Plugins fails on Linux SPARC with:

3: Test command: /<<PKGBUILDDIR>>/obj-sparc64-linux-gnu/BZIP2/test/read_ui8_test
3: Working Directory: /<<PKGBUILDDIR>>/obj-sparc64-linux-gnu/BZIP2/test
3: Environment variables: 
3:  HDF5_PLUGIN_PATH=/<<PKGBUILDDIR>>/obj-sparc64-linux-gnu/plugins
3: Test timeout computed to be: 1500
1/3 Test #1: HDF5:external_filters:LZ4 ..............Bus error***Exception:   0.04 sec

This indicates that the code contains unaligned access which can degrade performance on various non-x86 targets.
