libxml2 and threads

[Alex Dupre]

Building a threaded libxml2 library breaks many ports (at least php and 
xfce4). Many users enable threads in libxml2 blindly and then complain 
that port XXX doesn't work. With the addition of the new OPTIONS feature 
the WITH_THREAD knob appears to every user and we are costantly (at 
least one or two a day, privately or on mailing list) receiving messages 
about such failure. Is it possible to commit a change like the following?
