[meta-virtualization] [PATCH 3/7] xen: Newlib recipe and patches for Xen stubdoms

Regarding the patches, these files were not created by me. Instead, these
files were copied directly out of the Xen source tree. I was trying to
mimic the Xen/stubdom/Makefile targets/recipes and minimize the deviations
and any necessary maintenance to the files. I claim no ownership on the
implementation of the patches, so I'll modify the patchfiles as noted by
Bruce unless I receive direction otherwise.
Thanks for the feedback and comments.
