# This is normally ok (libcxx relies on an unwinder), but if libunwind is
# built in the same cmake invocation as compiler-rt and we're using the
# in tree version of runtimes, we'd be linking against the just-built
# libunwind (and the compiler implicit -lunwind wouldn't succeed as the newly
# built libunwind isn't installed yet). For those cases, it'd be good to
# link with --uwnindlib=none. Check if that option works.
