meson: Link against libc++ with compiling with clang

Browse source 
libc++ is used by Chrome OS, and likely as well by other environments
based on clang. Using it by default if available when compiling with
clang will help extending the compile-testing coverage. The drawback is
that issues specific to clang with libstdc++ will not be caught as
easily, but based on the experience with clang so far, code compiling
correctly with gcc/libstdc++ has failed with clang due to either
clang-specific or libc++-specific behaviour, never due only to the
combination of clang with libstdc++.
