If that's the case, I don't have any objection.  You may like to remove
the lines that "Save away all section symbol values", remove ksec var,
and remove the comment starting "That put the value right.."

Emit the eh_frame header and info for non-linkonce functions to
sections .eh_frame1, .eh_frame2, etc., bumping section number whenever
you hit a linkonce function.  linkonce eh info goes to
.gnu.linkonce.eh.*, without it's own header.  Then link with

  .eh_frame :
  {
    *(.eh_frame* .gnu.linkonce.eh.*)
  }

The idea being to actually remove the eh info along with the corresponding
linkonce text, and have the linker put everything else back together.

Oh, and fix the linker so that the above doesn't reorder anything
(linkonce sections currently get moved around, which I believe is a bug),
or plug in inconvenient padding for section alignment.
