I went looking for IMAGE_FILE_MACHINE_I386 in the pe_data and didn't find
it (it'd be cleaner than looking at bfd arch and machine and having to
mask off the bit for intel syntax).  I'll have to look again in the
debugger and see if I can find these values available at the time the
data directory is being filled in.
