Here's another fix for mn10300 relaxation problems.  We did function
relaxation using custom calling conventions (i.e., merging movm into
the caller) even for dynamic symbols.  Also, C++ thunk code calls a
local alias to a global function, so we relaxed the thunk without
realizing we were actually relaxing the global function.  Can't do
that.  I'm not entirely sure this patch will cover correctly all cases
(e.g., can we ever decide to use custom calling conventions for a
global symbol?), but this significantly improves C++ test results with
-mrelax, so I'm going ahead and checking it in.
