We don't just do bfdcore_write -- we actually create a core file
from the memory image, and then add an extra segment to it for
bfdcore_write to write into.  The core file is an integral part
of the execution log file.

I forgot to post the accompanying changes to gcore.c with this
patch.  I'm just about to put them up now that Hui reminded me.
