This is essentially a compile-time assertion to make sure we have the correct 
value for `FPE_FLTIDO`. If we're building on an older FreeBSD which does not 
have it defined then we can't check it anyway.

We could run an LLDB built on older FreeBSD on a newer kernel and receive 
`FPE_FLTIDO` I imagine.
