/root/kata/qemu-lite/qga/commands-posix.c:660:13: error: In the GNU C Library, "minor" is defined
 by <sys/sysmacros.h>. For historical compatibility, it is
 currently defined by <sys/types.h> as well, but we plan to
 remove this soon. To use "minor", include <sys/sysmacros.h>
 directly. If you did not intend to use a system-defined macro
 "minor", you should undefine it after including <sys/types.h>. [-Werror]
         *devminor = minor(st.st_rdev);

解决方案：config之后自动生成config-host.mak文件，在文件QEMU_CFLAGS=的最后加上-Werror=format-truncation=0
