unicore32-softmmu: Add unicore32-softmmu build support
This patch adds unicore32-softmmu build support, include configure, makefile, arch_init, and all missing functions needed by softmmu. Although all missing functions are empty, unicore32-softmmu could be build successfully. By 20120804: change QEMU_ARCH_UNICORE32 to 0x4000 Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
