14f18b7f7e On 24K we did always disable cache parity protection - obviously not 
the greatest thing to do.  Try to enable parity protection, check if
we actually succeeded and print a message about the outcome of this.

784f7b9d89 Fix 'prctl' system call for IRIX. At this point IRIX 5.3 static binaries 
are now working for 80% of the ones I have tried. The other ones that do
not work all fail in the same way with the same messages. Once that bug
is tracked down, we should be in good shape. Task locking still needs
some work.

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.
