Ulrich Drepper c70ca1fa69 Update.
* sysdeps/unix/sysv/linux/powerpc/pread.c: Do not use the i386 version.
	Instead call the system call wrapper function using an 64bit argument.
	* sysdeps/unix/sysv/linux/powerpc/pread64.c: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/pwrite.c: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/pwrite64.c: Likewise.
