There isn't a standard test for detecting whether or not -mieee is
available (at least, none that I know of).  The only workarounds that I've
found were when someone used the host detection bits and conditionalised
on them.  As for what ARCH should be...probably "alpha*-*-linux-*" would
be best (since alpha* is too generic and Tru64 would be impacted).
