[for-10.0,15/25] tests/fp: Explicitly set 3-NaN propagation rule

Commit Message

Peter Maydell Nov. 28, 2024, 10:43 a.m. UTC

Explicitly set a rule in the softfloat tests for propagating NaNs in
the muladd case.  In meson.build we put -DTARGET_ARM in fpcflags, and
so we should select here the Arm rule of float_3nan_prop_s_cab.
