clang: Fix native and nativesdk builds for hf targets

Setting the ${HF} variable based on ${TUNE_CCARGS_MFLOAT} does only make sense
for target builds, as it defines arguments for target.  Without this fix,
building with hf machine configuration will cause problems, as native and
nativesdk triplets will be include "hf", something like "x86_64hf-linux", which
is wrong and not recognized by LLVM build/configuration system.
