Ok, my suggestion to use the linker was not a "do it this way", it
really was just a "maybe alternate approach". So no objections if
absolute_pointer() ends up being the simpler solution.

What other notable issues end up being still live? I sent out that one
patch for sparc, but didn't get any response to it. I'm inclined to
just apply it (the 'struct mdesc_hdr' pointer misuse one).
