The test failures are complaining not finding python: I don't think they are related to my change - more like an infra issue. I can rebase the changes and try again. |

…chain config `static_link_cpp_runtimes` is one of the well-known features - which is required if you want to link in non-default toolchain libs. However the default unix toolchain does not define it at all. This PR adds a simple definition of this feature. The added feature is disabled by default to avoid negative impacts, and can be enabled on demand. Closes #17391. PiperOrigin-RevId: 507677235 Change-Id: If149a50c1ab41dad258f706bc83df0fc09f8e6e7

This patch implements the `static_link_cpp_runtimes` feature in `unix_cc_toolchain_config`. The feature is documented as a well-known feature[1] and was added to the toolchain[2] but not implemented. The patch follows the solution proposed on GitHub.[3] For the feature to work as expected, users have to remove the linker flag `"-lstdc++"` from `link_libs` (or `link_flags`) from the call to `unix_cc_toolchain_config`.
