Nothing I can do about this, sorry. The bison_cc_library rule has a hard dependency on the new C++ toolchain, which is available in Bazel v0.22. It's scheduled to release next week (bazelbuild/bazel#6494) so either wait until then, or use the bison() rule and define the cc_library separately:

bison(
    name = "parser_srcs",
    src = "parser.y",
)
cc_binary(
    name = "parser",
    srcs = [":parser_srcs"],
)
