Move arm port to ports repository cvs/fedora-glibc-20050524T1606
2005-05-23  Roland McGrath  <roland@redhat.com>

	* sysdeps/arm, sysdeps/unix/arm, sysdeps/unix/sysv/linux/arm:
	Subdirectories moved to ports repository.
	* configure.in (base_machine): Remove arm* and thumb* patterns.
	* shlib-versions (arm.*-.*-linux.*): Remove this pattern.
