Given that the hard-float ABI essentially requires V4SF as a type, it might be

If the testcase is built with -march=armv8.1-m.main+mve.fp then the useless

Almost certainly this is related to the need for a copyreloc and presumably the
linker has not created one for some reason. So I suspect this is most likely a
binutils issue rather than a compiler one.
