By commit 67a1de0d, When we perform 'git pull && make && sudo make install', In 'make' stage a qemu-version.h.tmp will be generated. If the content of qemu-version.h.tmp and qemu-version.h aren't consistent, The qemu-version.h.tmp will be renamed to qemu-version.h. Because of the target FORCE, The same action will be do again in 'make install' stage. In 'make install' stage, If there is no qemu-version.h.tmp exists and we run 'make install' with sudo, The owner and group of new qemu-version.h.tmp will be privileged user/group. When we run 'make' next time, qemu-version.h.tmp can't be overwritten because of permission issue. This patch removed qemu-version.h.tmp after build to fix this issue.
