a bad attempt at trying to trying to host an array with the frames from bad apple in it to try to shove < into tixy.land

Extremely unclear to me what the difference between some of the @rules_cc and @bazel_tools things are supposed to be:

@bazel_tools @rules_cc
@bazel_tools//tools/cpp:current_cc_toolchain @rules_cc//cc:current_cc_toolchain
@bazel_tools//tools/cpp:toolchain_utils.bzl:find_cpp_toolchain @rules_cc//cc:find_cc_toolchain.bzl:find_cc_toolchain
@bazel_tools//tools/cpp:toolchain_type @rules_cc//cc:toolchain_type

@rules_cc//cc:find_cc_toolchain.bzl:find_cc_toolchain returns a CcToolchainInfo (documented here). @bazel_tools//tools/cpp:toolchain_utils.bzl:find_cpp_toolchain claims it returns a CcToolchainProvider ([not officia

bazel toolchain_transition_test (non-native – not rules_cc)
non-native – not rules_cc
the point is to see whether we can have a toolchain depend on another toolchain of the same type (using transitions) without Bazel thinking it's a cycle
i.e. bootstrapping
the answer appears to be yes; we can do this (without needing to resort to manually running commands from a repo rule or something)
this doesn't seem to work with rules_cc; a native ruleset
but it's not super clear why
