[PATCH] sparc64 crt{begin,end}{,S}

Hi!

There is no reason why glibc should provide these when gcc provides them,
and they don't work correctly (e.g. using the glibc crt* the libpthread
constructor is never called).

	* sysdeps/sparc/sparc64/elf/Dist: Remove.
	* sysdeps/sparc/sparc64/elf/crtbegin.S: Remove.
	* sysdeps/sparc/sparc64/elf/crtbeginS.S: Remove.
	* sysdeps/sparc/sparc64/elf/crtend.S: Remove.
	* sysdeps/sparc/sparc64/elf/crtendS.S: Remove.
	* sysdeps/sparc/sparc64/elf/Makefile: Don't build crtbegin/crtend
	objects.
