It changed because mksysinfo.sh now unconditionally defines IPMreq.  I
did that because it is needed in order to compile the net package, and
RTEMS doesn't define it at all.  We can get away with this on Irix
because the definition is pretty much the same on all systems.

I committed your patch to socket_irix.go.

Thank.
