This is quite confusing.
`-m[no]-v8plus` is an environment option, similar to X86's `-mx32`, but imposes
more restrictions.
`-mcpu=v9 -mno-v8plus` should be equivalent to just `-mcpu=v9` because 64-bit
environment is the default for 64-bit ISA.
`-mv8plus` enables 32-bit environment and therefore should restrict the
compiler from using the whole set of V9 features. That is, I would expect it to
disable something rather than to enable `v9`, which should already be set by
`-mcpu=v9`.
