One could add a -mtune-fpu switch. Did you look at other architectures in the
GCC tree that would have similar requirements?
Thank you for the suggestion about adding a -mtune-fpu switch. I have
not yet looked at the other architectures, but will do so before proceeding.

Like this, applied on all branches.

Why not use leon instead of leon3 for them?

Early variants of LEON3, revision 0, do not support the CASA instruction.
This patch adds two new targets, leon3r0 and leon3r0v7, that are equivalent
to leon3 and leon3v7, except that they do not support CASA.
