Add C++ toolchain configuration for OpenBSD.
In my limited testing, these changes appear to work. When I built Bazel on OpenBSD incorporating these changes, the resulting `bazel` binary could build C++ libraries and binaries. Likewise on FreeBSD.
This change, split out of the larger PR https://github.com/bazelbuild/bazel/pull/10274, is part of the OpenBSD port in https://github.com/bazelbuild/bazel/issues/10250.
Closes #10436.
