Make the bootheader for ppc64 independent from kernel and libc headers. * add -nostdinc -isystem $gccincludes to not include libc headers * declare all functions in header files, also the stuff from string.S * declare some functions static * use stddef.h to get size_t (hopefully ok) * remove ppc32-types.h, only elf.h used the __NN types With further modifications by Paul Mackerras and Stephen Rothwell.
