	* gdbarch.sh (elfcore_write_linux_prpsinfo): New F hook.
	(struct elf_internal_linux_prpsinfo): Forward declare.
	* gdbarch.h, gdbarch.c: Regenerate.
	* linux-tdep.c: Include `cli/cli-utils.h'.
	(linux_fill_prpsinfo): New function.
	(linux_make_corefile_notes): Use linux_fill_prpsinfo.  If there's
	an elfcore_write_linux_prpsinfo hook, use it, otherwise, use
	elfcore_write_linux_prpsinfo32 or elfcore_write_linux_prpsinfo64
	depending on gdbarch pointer bitness.
	* ppc-linux-tdep.c: Include elf-bfd.h.
	(ppc_linux_init_abi): Hook in elfcore_write_ppc_linux_prpsinfo32
	on 32-bit.
