Subject: [svn-r12172] Purpose: configure refactoring

Description:
Migrated a couple of Fortran macros to standard autoconf macros

Solution:
HDF5 had a couple of macros, AC_TRY_FLINK and AC_CHECK_FLIB, which were
adaptions of standard autoconf macros before those macros supported
F90.
Now Autoconf seems to have better support for f90, so its standard macros
AC_TRY_LINK and AC_CHECK_LIB can do this job (and move the burden of
supporting those macros to autoconf).

Platforms tested:
heping, modi4, copper
