  I don't know how to make this works in cross compilation schemes.
How on the build host could libxml2 configuration learn about the
specific flags used by your ARM target version ? I have no idea,
if you don't either, I guess disable Python until you can build
natively ! Or check how other projects do and suggest a way to do
things, but in a nutshell, I don't know !
