Benjamin Herrenschmidt c5f5f50738 hello_world: Use new headers and frequency from syscon 
This uses the new header files for register definitions and
extracts the core frequency from syscon rather than hard coding it.

Paul Mackerras cf4dfeca36 Change the default cross compiler prefix to powerpc64le-linux-gnu- 
That is what is used by the packaged cross-compilers on (at least)
Fedora and Ubuntu.

Paul Mackerras abefafd70b hello_world: Adjust header inclusions and Makefile 
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.
