[PATCH v2 1/4] Remove obsolete ARC system

[Anton Kolesov]

Hi,

Resending my patches as attachments - these are pristine .patch files
without filtering out "configure" file changes. 

ARC architecture specific files has been added ages ago in newlib/libc/sys,
but with invention of libgloss those files should be moved from newlib to
libgloss.
