Error while testing

I'm not sure if it's related to the project, but I'm getting the following error at make tests:

In file included from matcopy.c:33:

      |     ^~~~~~~~

I have investigate this and it looks like "bfloat16" is not defined in any of the headers of OpenBLAS. It is defined in the source tree, but not in the interface.

[openblas/include]$ grep bfloat *
f77blas.h:         bfloat16 *, blasint *, bfloat16 *, blasint *, float *, float *, blasint *);

So none of the files in that directory define that type and non of the includes contain such definition. The interface is either incomplete or assuming a compiler with a built-in type called "bfloat16".

The issue with OpenBLAS should be avoided in v1.16.1; feel free to reopen/create another issue if you encounter a problem. Thank you very much for your contribution and report!
