Verified on x86_64-linux-gnu and i686-linux-gnu that no libc.so code
changes.

Thanks,
Roland


	* sysdeps/unix/sysv/linux/x86_64/clone.S: Deconditionalize the code
	that was previously under [RESET_PID].
	* sysdeps/unix/sysv/linux/i386/clone.S: Likewise.
	* nptl/sysdeps/unix/sysv/linux/x86_64/clone.S: File removed.
	* nptl/sysdeps/unix/sysv/linux/i386/clone.S: File removed.
