right.

No, that's not how things are supposed to work. Look at c99_runtime for
example: we have both
dg-require-effective-target c99_runtime
which checks if the targets supports a C99 runtime, and
dg-add-options c99_runtime
to add special options for targets that need them.
I've no idea why this isn't the case for ieee today.
