The branch information in my copy-pastes was indeed wrong but I also
tried the branch you mention:
origin git://xenbits.xen.org/people/ianc/xen.git (fetch)
branch arm-cross
latest commit: 6e258f232d5c4409a549f2b03651bb289703aab7

I have the same issue. I think I miss something, I don't understand
what you reference to with 'series'? Also I think this python issue
isn't related to the glibc version mismatch, or does your build use an
older version ( one that's shipped with debian wheezy )?

Thanks a lot for you help!
