	* libc.map: Add _dl_profile.
	* elf/dl-reloc.c (_dl_relocate_object): Take extra argument, pass
	this to ELF_DYNAMIC_RELOCATE.
	Always allocate array for relocation result if LD_PROFILE is defined.
	* elf/ldsodefs.h: Adjust prototypes.
	* elf/dl-open.c (_dl_open): Call relocation function with extra
	argument.
	* elf/rtld.c: Likewise.
	* elf/dl-profile.c (_dl_mcount): Don't mark as internal function.
	Correct loop condition.
	* elf/dynamic-link.h: Don't examine _dl_profile variable, pass
	consider_profile to runtime setup function.
	* sysdeps/i386/dl-machine.h (elf_machine_runtime_setup): Use
	_dl_runtime_profile for all shared objects if LD_PROFILE is defined.

	* elf/dl-support.c: Define __libc_stack_end.
	* elf/rtld.c: Likewise.
	* sysdeps/generic/libc-start.c: Store last stack address in

	Include <stdint.h>, not <inttypes.h>.

	* elf/sprof.c: Implement flat profiling.
