Moved alpha to ports repository.

2008-11-25  Roland McGrath  <roland@redhat.com>

	* sysdeps/alpha, sysdeps/unix/bsd/osf/alpha,
	sysdeps/unix/bsd/Attic/osf1/alpha, sysdeps/unix/sysv/linux/alpha,
	sysdeps/unix/sysv/linux/alpha/alpha, sysdeps/unix/alpha,
	sysdeps/mach/alpha, sysdeps/mach/hurd/alpha:
	Subdirectories moved to ports repository.
	* configure.in (base_machine): Remove alpha case.
