[svn-r20504] Purpose:

    General shared library improvements for CYGWIN / AIX

Description:

    Shared libraries are disabled on both CYGWIN and AIX due
    to inability to build them correctly. Part of the problem
    in both of these situations is the lack of the libtool
    flag -no-undefined, which tells libtool that all needed
    symbols are defined at link time (a requirement on these
    systems) and that it's okay to build shared libraries.

    Another problem are lack of dependencies between wrapper
    libraries and core C HDF5 library.

    This patch addresses both of these by fixing configure to
    add in -no-undefined flag for libtool during linking and
    adds automake dependencies in the Makefile.am files.

    After testing, both CYGWIN and AIX now generate shared
    libraries, but there are still some test failures in each.
    (cache_api, dt_arith, and testerror.sh on CYGWIN, and
    fortran tests on AIX).

    Even though the shared libraries are not quite perfect,
    this is a general improvement to what we had before, so
    I'm applying the patch anyways. Note that default behavior
    of shared libraries on these systems being disabled has
    NOT been changed and requires the use of the
    --enable-unsupported to attempt to build them.

    We will need to address the test failures in each
    architecture prior to formally supporting shared
    libraries on each.

Tested:

    h5committested & CYGWIN tested (on bangan)
    (AIX tested by Albert on bp-login2)
