In particular note that the function:
symfile.c:init_entry_point_info() which sets up all the
objfile->ei.deprecated_entry_file* is seriously screwed up for PIE
files anyway.

In such a case we need to figure out where the program got loaded,
just like a shlib, the main executable is not marked as EXEC in the
elf header anymore, and lots of other fun stuff. Anyway, the way the
entry file/entry point stuff is handled now won't work for PIE.

I am currently working on PIE support, BTW. I'll post something as
soon as I have some coherent story.
