Improve the search of the clang instance for CUDA.

Browse Source 
Before, it was not possible to find the clang++, which is contained in the cling, if we don't start the clang from the bin folder ('./cling -xcuda'). Now, for example it is possible to start the cling with 'bin/cling -xcuda' .

Fix a Bug, which avoid to start './cling -xcuda -fsyntax-only'.
