	Reformat copyright.

	* elf/rtld.c (_dl_start): Don't dereference the value returned by
	elf_machine_got to get _DYNAMIC, instead call new function
	elf_machine_dynamic.
	* sysdeps/alpha/dl-machine.h: Permute elf_machine_got to
	elf_machine_dynamic.  Reformat copyright.
	* sysdeps/i386/dl-machine.h: Likewise.
	* sysdeps/m68k/dl-machine.h: Likewise.
	* sysdeps/mips/dl-machine.h: Likewise.

	* Makerules ($(libdir)/libc.so): Make first line of generated
