CBLAS_TRANSPOSE

Building on Ubuntu 22.04 with the following command: ./build_oai -C --phy_simulators

Results in multiple compilation errors such as:

/home/oai/develop/openairinterface5g/openair1/PHY/LTE_UE_TRANSPORT/linear_preprocessing_rec.c:234:3: error: unknown type name ‘CBLAS_TRANSPOSE’; use ‘enum’ keyword to refer to the type
  234 |   CBLAS_TRANSPOSE transa = CblasNoTrans;
      |   ^~~~~~~~~~~~~~~
      |   enum

If you change CBLAS_TRANSPOSE by enum CBLAS_TRANSPOSE in the related source file (linear_preprocessing_rec.c) the compilation errors will be fixed and the phy_simulators will be fixed.
