linux-user: Fake /proc/cpuinfo
Fedora 17 for ARM reads /proc/cpuinfo and fails if it doesn't contain ARM related contents. This patch implements a quick hack to expose real /proc/cpuinfo data taken from a real world machine. The real fix would be to generate at least the flags automatically based on the selected CPU. Please do not submit this patch upstream until this has happened.
