Clear CXX and TEST_CXX if C++ link test fails
Since the C++ compiler is used only for testing, use TEST_CXX as the C++
compiler if available. If C++ link test fails, clear both CXX and
TEST_CXX so that the C++ compiler isn't used for glibc build nor test.
Tested for m68k-linux-gnu-coldfire build and native build on x86-64.
