V2SF should normally be defined by ABC/ABC-modes.def. It is normally
found by these lines in config.gcc when you run configure:
if test -f ${srcdir}/config/${cpu_type}/${cpu_type}-modes.def
then
extra_modes=${cpu_type}/${cpu_type}-modes.def
fi
V2SF will be created by the line
VECTOR_MODES (FLOAT, 8);
in ABC-modes.def (as copied from mips-modes.def).

Hard to say without knowing what you changed. Did you simply delete
the ANYF macro, or forget to remove the V2SF case from it?
