not really, what its telling is that you dont have
callconvention-hard in TUNE_FEATURES
which means that compiler wont use hardfloat ABI when making function calls.
but neon/vfp will still be used e.g. when doing vectorization etc. if
using hardfp ABI will radically improve performance totally depends
upon kind of workload that you are measuring. It may vary.
