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.

85b6e8184b Rewrite to avoid the use of $at. Unfortunately binutils 2.15 and CVS 
binutils are broken and don't warn about this use of $at even though
gas is in .set noat mode so this for now is an accident waiting to
happen.
