Having issue compiling both BUILD_HFLOAT16 and BUILD_BFLOAT16 at the same time

[ChipKerchner]

When both flags are present, I get these errors:

Can't look right now, but I hope we're not getting a conflict in our definition of IFLOAT

[martin-frbg]

cmake/utils.cmake does not know to pass the HFLOAT16 define yet - I'll prepare a fix after confirming that it is sufficient to build on Banana Pi F3

Thanks! Looks great. Works for me
