Generated header file contains cblas function delcarations when cblas is disabled !!

[kvaragan]

When config with "--disable-blas --disable-cblas ..". In the generated .a file, indeed there is no cblas related symbols. However, in the generated header file, there are still cblas related function declarations. Is it possible to remove those cblas related function declarations in the generated header file when we config with "--disable-blas --disable-cblas"?
