... and doing merging will break unused section elimination; and on ARM
potentially create sections that are then too large for proper
long-branch veneers to be inserted.
So I think what we really need here is another option (groan), that
controls whether ld -r merges sections. In my opinion merging should be
off by default (it appears you already have to add other flags if you
want ld -r to do other additional things like allocate common data).
