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.
