Patch providing proof-of-concept implementation

I attach a patch implementing this change on svn HEAD.  It doesn't break any
tests here, but I am fairly sure I've done the wrong thing to the linker script
(gnu.ver); I don't really understand the linker script, so it was rather
monkey-see-monkey-do.
