h5cc link-line reordering
Description:
Re-ordered flags in h5cc such that LDFLAGS appears after hdf5 library
include path. This is to ensure third party library locations don't
interfere with locating the correct version of hdf5 library.
Tested:
passed daily tests in 1.8 branch (as verified by Larry just now).
