OpenMP offloading to VE requires a cross-compiled OpenMP runtime and compiler-rt.

The compiler-rt files need to be placed in the build directory to run the tests, but the OpenMP runtime can be placed elsewhere with the CMake variable LIBOMPTARGET_OPENMP_HOST_RTL_FOLDER pointing to it.
The patch uses this CMake variable to set the library search path and the runtime VE_LD_LIBRARY_PATH environment variable for VE tests.
