directly into their target location, because the monitor
ROM for the GHS Multi debugger barfs if we try.
Unfortunately, Multi also doesn't deal correctly with ELF
sections where the LMA and VMA differ (it just ignores the
LMA), so we can't use that feature to work around the
problem! What we do instead is just put the interrupt
vectors into a normal section, and have the
`mach_early_init' function for Midas boards do the
necessary copying and relocation at runtime (this section
basically only contains `jr' instructions, so it's not
that hard). */
