Updates to hdf5 automake macro

Two updates:

• Got new version of the ax_lib_hdf5.m4 macro. I have ported our changes to that new version.
• Fixed an issue encountered on the HLRS system. Their h5cc -show call returns a multi-line output which was then assigning a multi-line output to $HDF5_CC which then creates a problem in the generated Makefile.

What do you think?

• 6703191b - Use simple head -n, that is POSIX

Compare with previous version

So your use of $HEAD was broken, which meant it only looked like it worked (remarkably). Can you check that this still works on HLRS.

Just so that I understand, the issue is that $HEAD may not be defined?

There is no test for the head command, so never defined.

Thanks. That update works on the HLRS machine.

Good, will accept.
