alpha/clone.S: Invoke .set noat/.set at around explicit uses of $at
On Alpha, the register $at is, by default, reserved for use by the assembler, in the expansion of pseudo-instructions. It's also used by the special calling convention for _mcount. We get warnings from Alpha clone.S because the code to call _mcount isn't properly marked up to tell the assembler not to use $at itself. * sysdeps/unix/sysv/linux/alpha/clone.s (__clone): Wrap manual uses of $at in .set noat / .set at.
