Teach CMakeDetermineCompilerId to recognize the Tegra-Android platform and generate a test project for Nsight Tegra tools. Locate the full path to CMAKE_<LANG>_COMPILER by computing it within the test project build environment. Also teach CMakeFindBinUtils that this variant of the Visual Studio generator uses UNIX-like instead of MS-like archiving and linking tools.
