"Tentative libcroco fix for Mac OS X --without-system-libxml"

things look good now at least for my Mac OS X 10.6.8 master build 
(--enable-binflter --enable-dbgutil --enable-ext-scripting-beanshell 
--enable-ext-scripting-javascript --enable-python=internal 
--without-system-libxml, make check):

$ find solver -type f -exec bash -c 'otool -L "$0" 2>/dev/null | grep -F 
libxml2 && printf "^^^ %s ^^^\n" "$0"' {} \;

shows that only a handful of executables and dynamic libraries use 
system libxml (/usr/lib/libxml2.2.dylib or 
/usr/local/lib/libxml2.2.dylib)---all of which are apparently only used 
during the build (if at all) and not included in the installation set 
(see below).  Also, URE libraries correctly reference libxml2 via 
@loader_path/libxml2.2.dylib, while libraries from the program directory 
correctly use @loader_path/../ure-link/lib/libxml2.2.dylib.

I suggest to review the above three commits and cherry-pick them into 
libreoffice-3-5 and libreoffice-3-5-0.
