invalid target error in c674x dsplib

Hi TI,

In the latest C674x dsplib, an internal error will lead to build error.

In file: C:\ti\dsplib_c674x_3_2_0_1\packages\ti\dsplib\src\DSPF_sp_mat_mul_gemm_cplx\DSPF_sp_mat_mul_gemm_cplx.h

#if defined(_TMS320C6600)
#include <ti/dsplib/src/DSPF_sp_mat_mul_gemm_cplx/c66/DSPF_sp_mat_mul_gemm_cplx.h>
#else
#error invalid target
#endif

In a C674x DSP platform, we don't set the MACRO definition _TMS320C6600, so the compiler will report an error here. So there might be some things missing here, like:

#if defined(_TMS320C6600)
#include <ti/dsplib/src/DSPF_sp_mat_mul_gemm_cplx/c66/DSPF_sp_mat_mul_gemm_cplx.h>
#elif defined(_TMS320C6740)
#include <ti/dsplib/src/DSPF_sp_mat_mul_gemm_cplx/c674/DSPF_sp_mat_mul_gemm_cplx.h>
#else
#error invalid target
#endif

The same problem was found in C:\ti\dsplib_c674x_3_2_0_1\packages\ti\dsplib\src\DSPF_sp_mat_mul_cplx\DSPF_sp_mat_mul_cplx.h

Please check and correct them.

Thanks,

Allen
