Fix building Tensorflow on RISC-V 64 with GCC13+.

Fix building with GCC13+.

This commit fixes #102159 which prevented TensorFlow from compiling on RISC-V 64 due to missing codepath in the build system.

RFC: Currently this patch overrides timeout of rules_python for all platforms which is obviously not ideal. How do we set pip package timeout here in Tensorflow?
