	* sysdeps/unix/sysv/linux/sparc/sparc64/bits/time.h: Move to...
	* sysdeps/unix/sysv/linux/sparc/bits/time.h: ...here.
	* sysdeps/unix/sysv/linux/sparc/sparc32/sparcv9/bits/time.h: Remove.
	* sysdeps/unix/sysv/linux/sparc/sparc64/bits/socket.h: Move to...
	* sysdeps/unix/sysv/linux/sparc/bits/socket.h: ...here.  Adjust
	struct msghdr for __WORDSIZE == 32.
	* sysdeps/unix/sysv/linux/sparc/sparc64/bits/statvfs.h: Move to...
	* sysdeps/unix/sysv/linux/sparc/bits/statvfs.h: ...here. Adjust
	for __WORDSIZE == 32.
	* sysdeps/unix/sysv/linux/sparc/sparc64/bits/siginfo.h: Remove.
	* sysdeps/unix/sysv/linux/sparc/sparc32/sparcv9/get_clockfreq.c: New
	file.
	* sysdeps/unix/sysv/linux/sparc/sparc64/longjmp.S (__libc_siglongjmp):
	Rename from longjmp, make longjmp weak alias to it.
