[PATCH] Allow building GCC with PTX offloading even without CUDA being installed (gcc and nvptx-tools patches)

Hi! This is something that has been discussed already during the last Cauldron. Especially for distributions it is undesirable to need to have proprietary CUDA libraries and headers installed when building GCC. These two patches allow building GCC without CUDA around in a way that later on can
