Details:

Hello,

there is a (likely) copy&paste error in m4/ax_lib_hdf5.m4
that affects Fortran:

When deriving HDF5_FFLAGS and HDF5_FLIBS from the output of
"h5fc -show" (or h5pfc -show), both -Idir and -Ldir are
added to HDF5_FFLAGS.  However, -Ldir should be added to
HDF5_FLIBS instead.  Some compilers (e.g. flang) are unhappy
when they see both -c and -L on the command line.

Furthermore, it is possible that the Fortran hdf5-libraries and
module files are installed in a directory separate from the
C versions.  Therefore -Ldir should be added in front of
HDF5_FLIBS.

The attached patch attempts to fix this.

Thanks,
Harald
