We need c-torture.exp in order to set-torture-options; we need to 
set-torture-options to get the right list of variants, as otherwise we lose "-Og 
-g" (as I did in my original patch 13/14 for float16). However, I think we can 
drop the rest - here's v2, which I've cross-tested on aarch64-none-elf, 
aarch64_be-none-elf and arm-none-eabi:
