I consider that an experimental commit.  It's meant to solve the problems
we're having on a few very large compilation units with the limited length
of branches.  But if the cure turns out to be worse than the illness I'm
ready to pull it again.

A more proper patchset should modify the linker scripts to avoid the
excessive large number of sections you've noticed.  Somebody else is
currently working on a patchset to allow the --gc-sections ld option so
I decieded to take the path of least resistance for now.
