Good point. Unfortunately, I need to write into that variable, and the text
section is flagged as readonly.
Sadly, I misstated the problem and my hack doesn't even work.
I need the pe data space to be in *memory* prior to the text
section. Being in the file prior to the text section has no necessary
correlation to in memory relocation address. Hmm... gotta play
with ld a bit more.
