We print the path to C/C++ and NVCC compilers; makes sense to also print the path to SYCL compiler. ## If this is a bug, (1) what happens, and (2) what did you expect to happen? 1. `hipSYCL launcher:` is empty. 2. `hipSYCL launcher:` contains the path to the hipSYCL/ACpp launcher used during build.
