First of all, it's great to hear that libxml2 compiled at all and that most of 
the tests seem to pass.

That's the 'testapi' test which causes the same problem on Windows. The test 
should complete eventually. It's just incredibly slow. One possible 
explanation is that somewhere an array is reallocated every time an element is 
appended. Some Linux allocators can handle repeated reallocations in linear 
time, but in general, you have to expect quadratic behavior. I just haven't 
found the time to investigate the issue.
