Better patch to fix bug.
The previous work-around was brittle. I have implemented a better fix. Now a
trap table is generated that will by default jump to an address+offset that
represents the firmware trap table. RTEMS is able to install user ISRs to the
new trap table as expected, and any non-overridden trap handler will vector to
the firmware trap table.
