the shortfloat extension is only made of header files,
and hence do not require a library to be built.

`MPIX_C_FLOAT16` is defined as a synonym for `MPIX_SHORT_FLOAT`
if the C compiler supports `_Float16`, which is defined in
ISO/IEC JTC 1/SC 22/WG 14 N1945 (ISO/IEC TS 18661-3:2015).
This name and meaning are same as that of MPICH. This may be
a transitional datatype until the MPI Forum decides a proper
name for the type.

This extension provides additional MPI datatypes `MPIX_SHORT_FLOAT`,
`MPIX_C_SHORT_FLOAT_COMPLEX`, and `MPIX_CXX_SHORT_FLOAT_COMPLEX`
for `short float` (C/C++), `short float _Complex` (C), and
`std::complex<short float>` (C++), respectively, or their alternate
types like `_Float16`.
See `ompi/mpiext/shortfloat/README.txt` for details.
