	* sysdeps/unix/sysv/linux/sparc/bits/sigcontext.h: Clean up namespace.
	Lay out struct sigcontext according to what really gets passed on
	the stack.
	* sysdeps/unix/sysv/linux/sparc/sys/procfs.h: Don't include asm/elf.h.
	(elf_gregset_t, elf_greg_t, elf_fpregset_t, ELF_NGREG): Define.
	(prgregset_t, prfpregset_t): Define to elf_* types.
	* sysdeps/unix/sysv/linux/sparc/sys/ptrace.h (PTRACE_WRITEDATA):
	Define to correct value.
	* sysdeps/unix/sysv/linux/sparc/sparc32/profil-counter.h: Use struct
	sigcontext.
	* sysdeps/unix/sysv/linux/sparc/sparc32/sigcontextinfo.h: Likewise.
