[Buildroot] [PATCH 1/1] libxml2: add support for building host library with python support

[Vellemans, Noel]

Hi thomas,


>> I don't know if we want to introduce sub-options for host packages. 


Well, I first did HARD-code this option into my "test"-build, but based
on (a previous) patch from Will and based on the comments of Arnout, I
kind of did agree on the sub-option.
I know its not that good-looking, but at this time, it looks a
'reasonable' way of getting this done.


Ref to : [Buildroot] mesa3d:  "ImportError: No module named libxml2"


>>I'm confused here. I thought mesa required a Python that has xml2
support. But here you're building xml2 with Python support. 
>>Could you enlighten me? :-)

Please have a look at this 

http://lists.busybox.net/pipermail/buildroot/2012-November/061334.html

... Hope is clears out some questions...


Again, open to comments and/or better solutions, but at this time it
looked acceptable (if you ask me).


Regards Noel

I don't know if we want to introduce sub-options for host packages.

I'm confused here. I thought mesa required a Python that has xml2
support. But here you're building xml2 with Python support. Could you
enlighten me? :-)

Thanks!
