Currently hello_world fails to build with distro cross compiler packages such as Debian gcc-powerpc64-linux-gnu, because it doesn't provide string.h or unistd.h. In fact we don't need them, we just need stddef.h. This adds #include <stddef.h> to console.h to get size_t defined. We also add #include "console.h" to console.c. The hello_world Makefile currently hard-codes CROSS_COMPILE on non-PPC machines. This means that a command like: $ CROSS_COMPILE=powerpc64le-linux-gnu- make doesn't do what you expect; it just tries to use powerpc64le-linux-gcc regardless. Adding a '?' makes it do what one expects. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>
