7ee8798f37 Until I figure out why NFS filesystems are having problems with 
the 'load_irix_binary' and having kernel faults, Irix support is
disabled. I suspect locking of some sort, but I will now have to
investigate further.

Static IRIX binaries are now being detected properly and are using the
ELF interpreter found in this file.
