This is a proof of concept, for moving the benchmark suite to use
[nanobench](https://github.com/martinus/nanobench.git), which is a
single header file but gives some great advantages over the existing
benchmark suite:

* Robustness - nanobench will explicitly tell you when benchmarks are
  unstable, and offer some guidance to help stabilise them.
* JSON Output - this should allow us to store the results in a more
  machine friendly format, in future we can integrate this into CI to do
  checks on PRs

to fix linking problems with (at least) the AMD version of flang that creates dependencies on more than just the fortran runtime.

This patch is to enable benchtest for half precision gemm
when BUILD_HALF is set during make.
