known possible problems: (1) on ELF, apparently end, edata,
etc. are absolute. Not sure ignoring them here is a big
deal, but if we want to use them, the fix would go in
elfread.c. (2) I think shared library entry points on the
NeXT are absolute. If we want special handling for this
it probably should be triggered by a special
mst_abs_or_lib or some such. */
