LibXML2 config doesn't specify lzma as a dependency, which breaks
cross-compilation builds using new linkers (ld 2.21 or higher).
There is a bug on libxml2 to fix that, but since it's going to take a while
for things to go round and back, so we should have a harmless addition of the
library until then.
This breaks Clang's c-index-test cross-build.
