The default is True.

additonal_shell_toolchain_mappings: mappings of the shell toolchain functions to

Please refer to example in @rules_foreign_cc//toolchain_examples.

|
additonal_shell_toolchain_package: a package under which additional toolchains, referencing

|
the generated data for the passed additonal_shell_toolchain_mappings, will be defined.
|
|
This value is needed since register_toolchains() is called for these toolchains.
