[Xen-devel] [PATCH] stubdom: support Mini-OS config for Mini-OS apps

[Juergen Gross <jgross@xxxxxxxx>]

Mini-OS apps need to be compiled with the appropriate config settings
of Mini-OS, as there are various dependencies on those settings in
header files included by the apps.

Enhance stubdom Makefile to set the appropriate CPPFLAGS when calling
the apps' make.
