Merge pull request #584 in HDFFV/hdf5 from ~DEROBINS/hdf5_der:minor_develop_fixes to develop * commit 'cbca178410215a1fd60e3de85c4810487e327f8d': Updated the --enable-debug/production handling in configure.ac so that it more reliably indicates that the configure option can no longer be used. Previously, using --enable-debug="", etc. would not trigger an error (even though such usage is unlikely). Added awk processing to remove extraneous whitespace from H5_ flags in configure.
