3) might be too hard, at least on RHEL6/ppc64 the randomization of mmap has
difference between smallest and largest address for one mmap is almost 1GB in a
few attempts I've done (0xfff79110000 to 0xfffb5010000).
BTW, the fatal_error ("had to relocate PCH"); doesn't print, but instead
segfaults, as line_map seems to be in some weird state prepared for the PCH
read already at that point, thus it is pointing into the new PCH slot already.
