Thorn requiring HDF5 should put a requires in their configuration.ccl 
file, and thus would have no need of this macro;  thorns using it 
optionally can have an optional in their configuration.ccl file and define 
their own macro there, thus do not need it.

After the next beta release this thorn will go live, and the old stuff in 
lib/make/extras will be deprecated, so at that point all thorns using HDF5 
should be converted to either use REQUIRES or OPTIONAL.
