hdf5_ep

[svn-r5944] 
Purpose:
    Bug fix
Description:
    Search path for include files to build h5test_fortran.a did not have
    hdf5_builddir and hdf5_srcdir directories. Compilation failed when
    scrdir configure flag was used.
Solution:
    Modified Makefile.in to include the directories into the search path.
Platforms tested:
    modi4 with srcdir on AFS and build dir in $SCR using --enable-parallel
    --enable-fortran flags.
