Even though the method is a bit strange, it works really well.

Hmmm I'd like to see if we could be more concise with this. I'd expect this to be the most important part:

  filegroup(
      name = "multicall_support_files",
      srcs = glob([
+         "bin/**",
          "libexec/**/*",
      ]),
  )

Theoretically, you should be able to use cc_args directory formatting to expose the directory path:

cc_args(
    name = "toolchain_exec_prefix",
    actions = [
        "@rules_cc//toolchains/actions:compile_actions",
        "@rules_cc//toolchains/actions:link_actions",
    ],
    args = [
        "-D",
        "{gcc_exec_prefix}",
    ],
    format = {"gcc_exec_prefix": "@gcc-linux-x86_64//:toolchain_root"},
)

@armandomontanez Do you have time to process this? When will it be ready? We've been waiting for so long. 😞

[armandomontanez]

Sorry for taking so long. I'm not super sure we need all of this. I'm happy to help figure out how to reduce this to be a bit more constrained to exactly what's needed. Do you have a quick way to reproduce the specific problems you're encountering and hoping to solve with this?

@armandomontanez The main issue right now is that the GCC within the rule_based_toolchain isn't working properly. I need to use a shell script to filter inputs or perform some other operations to get it to work.
