[svn-r19421] Reorganize compile scripts h5cc.in, h5fc.in and h5c++.in to put LDFLAGS in the correct place and to enable the script user to set and override CFLAGS, CPPFLAGS, CXXFLAGS, FFLAGS, LDFLAGS, and LIBS that take pprecedence over the library paths and compile flags from the hdf5 build.
Tested with h5committest on amani, heiwa, and jam.
