Strange MXCSR messages?

Ok, it should now be fixed. I removed the fnsave/fxsave instructions
from libc_r entirely... fxsave can't be used there anyway because
the FP state on the signal stack is not 16-byte aligned (it was causing
an infinite loop, which is another issue but one I'm not going to worry
about right now).
Now the kernel is 100% responsible for saving and restoring the FP state.
Now that its fixed, I also changed the kernel to SIGFPE a user
program that messes up the MXCSR.
