This seems like something that could get merged quickly with one > more sentence in the changelog. The SGX selftests use a custom linker script, tools/testing/selftests/sgx/test_encl.lds, to configure the resulting enclave binary so that it's loadable as an enclave more or less as-is. One of the things the script does is drop sections the selftests doesn't want, .note* sections being in that category. I don't recall exactly why the script drops sections; I assume it's to simply the loading process. Anyways, .note.gnu.build-id is collateral damage and the linker complains.
