    Handle ICU_LIBS as LIBADD, not LDFLAGS to prevent linking errors

For https://bugzilla.gnome.org/show_bug.cgi?id=677606
For https://bugs.gentoo.org/show_bug.cgi?id=417539

If libxml2-2.8.0 is built with --with-icu --with-python on a system that has an
older version of libxml2 installed, then during "make install", libxml2mod.so
gets relinked to the systemwide version of libxml2.so.2 instead of libxml2.so.2
from the build tree, and fails at runtime if symbol versions from the older
libxml2.so.2 are not available. This effectively makes it impossible to build a
libxml2-2.8.0 binary package on a system that does not already have
libxml2-2.8.0 installed.

Investigation by Rafał Mużyło and Arfrever Frehtes Taifersar Arahesis revealed
the cause of the problem to be that libxml2's configure was adding ICU_LIBS to
LDFLAGS instead of to LIBADD. This resulted in GNU libtool using the wrong
argument order in its relinking command that gets run during "make install".

To build on an Unixised setup:
   ./configure ; make ; make install
To build on Windows:
   see instructions on win32/Readme.txt

To assert build quality:
   on an Unixised setup:
      run make tests
   otherwise:
       There is 3 standalone tools runtest.c runsuite.c testapi.c, which
       should compile as part of the build or as any application would.
       Launch them from this directory to get results, runtest checks 
       the proper functionning of libxml2 main APIs while testapi does
       a full coverage check. Report failures to the list.
