Minor fix in ToolChainTest.cpp to allow user defined GCC toolchain.

If the user configured clang with a custom GCC toolchain that will take precedence on what the ToolChainTest.cpp expects to evaluate. 
This is fixed here by passing --gcc-toolchain= to the driver, in order to override any user defined GCC toolchain.
