It is a very tricky thing to do with the current Linux dynamic linker.
Those removed functions should be restored. The question is where
they come from. We can't use the old definiton since we want to use
the ones in libunwind. In glibc, we do

foo ()
{
  h = dlopen (libgcc)
  fn = dlsym (h, "foo");
  (*fn) ...
}

so that we can define foo in glibc as a wrapper for foo in libgcc.
Maybe we can do the same for libgcc.
