Subject: [PATCH] FRV: Fix the extern declaration of kallsyms_num_syms [try #2]

From: David Howells <dhowells@...hat.com>

Fix the extern declaration of kallsyms_num_syms to indicate that the symbol
does not reside in the small-data storage space, and so may not be accessed
relative to the small data base register.
