baee502ce2 Get rid of the eir struct mips_fpu_emulator_private member. It's 
never initialized been initialized anywhere, just saved to and
restored from signal frames so nonsense anyway.  As neat side effect
of being shared between all processors it was also abusable as a
nice covert channel between processes.

1d74f6bc85 __compute_return_epc() uses CFC1 instruction which might result in a 
coprocessor unusable exception since the process can lose its fpu

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.
