Kurt Bodiker b9f265377c xen: Newlib recipe and patches for Xen stubdoms 
Newlib provides a fast, C library optimized for embedded systems. In the
case of Xen stubdomains, we are using MiniOS. This Newlib recipe creates
static libraries that are cross-compiled against MiniOS, Xen, and LWIP
headers and subsequently used during the cross-compilation and linking
of PolarSSL, the stubdom specific GMP, TPM Emulator, and the Xen vTPM
and vTPM Manager stubdomains. The current Xen source code is hardcoded
to fetch a specific version of this package. The patch files originate
from the Xen/stubdom source tree. This recipe provides the flexibility
to change version or modify the patches.
