toolchain-funcs.eclass: fix tc-cpp-is-true() to work with clang

Clang's preprocessor likes to output a leading newline, which makes
the comparison always fail. GCC generates additional output with certain
flags (e.g. -ggdb3) as well. Hence, switch the test to trigger a
preprocessor error when the condition is not true and examine the exit
code.
