* Create the ISA interrupt vector glue file.

* The interrupt handlers are hardwired into vector.s and are attached
* at runtime depending on the data in ioconf.c and on the results of
* probing. Here we only need to generate the names of the interrupt
* handlers in an ancient form suitable for vmstat (the _eintrcnt label
* can't be expressed in C). We give the names of all devices to
* simplify the correspondence between devices and interrupt handlers.
* The order must match that in mkioconf.c.
