Labels as tool_path in CROSSTOOL

[excitoon]

Can we have a possibility to specify Labels as tool_path in CROSSTOOL's (possibly even being compiled in the same build)? That would be a great step towards hermeticness.

E.g.:

  tool_path: "@some_gcc//:bin/gcc"

As of bazel 0.23.0 CROSSTOOL is deprecated in favour of skylark cc_toolchain and cc_common.create_cc_toolchain_config_info. See here. However the same problem persists in the new implementation i.e.

tool_path(
    name = "gcc",
    path = "@some_gcc//bin:gcc",
),

Is not possible.

I would perhaps recommend editing the CROSSTOOL title to this issue to match the new toolchain skylark api, as it is more likely to receive support.

I am also interested in a fix or a workaround for this. I would be happy to create a more up to date descriptive issue if that were ok with you?

[excitoon]

Sure. I can not edit title from phone unfortunately.

I have added a new issue here #7746. If this doesn't cover your use case I'd keep this issue open.
