Log:
[libc++abi] Allow use just compiled clang++ for tests

Currently, the tests assume the system compiler is the one we want
to test, but if we build libcxxabi together with LLVM+Clang, it'll
get the wrong compiler.

This patch allows us to test if we have clang++ in our /bin directory,
and if so, use it.
