	* sysdeps/unix/sysv/linux/sparc/sparc64/pipe.S: Set branch
	prediction correctly.

	* sysdeps/unix/sysv/linux/sparc/sparc32/profil-counter.h: Signal
	takes a pointer to __sigcontext_t.
	* sysdeps/unix/sysv/linux/sparc/sparc64/syscall.S: Do a nop after retl.
	* sysdeps/unix/sysv/linux/sparc/sparc32/Dist: Remove fork.S.
