This patch is OK.  There are still things wrong with the stubs, but it
fixes some and doesn't introduce new problems.

FYI, we (CodeSourcery) need a version of the new stub code that works
on all our targets this week.  So I plan to review the output for as
many cases as I can think of on Monday.  We're also working on a patch
to put the stubs after input sections instead of before, as you and I
discussed last year.

Am I correct that most (or all?) places this function returns
arm_stub_none, we'll still generate out-of-range branches?
