Let me add a combination here: Ghostscript 10.01.0 built from current
git (commit 462efa959) yields 28MB with extractpdfmark and working
links (AFAICT), without changes to LilyPond. The reason is likely
http://git.ghostscript.com/?p=ghostpdl.git;h=073c1adebeef38317ae0e6cb0f6d366ddaadb38a
(the linked bug number is wrong, the correct one is
https://bugs.ghostscript.com/show_bug.cgi?id=705996 ).

Which proves that extractpdfmark works with the new PDF interpreter
(modulo bugs), and the size issue is unrelated (and still unfixed).
QED.
