When building with clang, the unittests were giving us an error: ``` error: undefined symbol: llvm_gcda_start_file ``` This seems to be from linking in `gcov` regardless of the toolchain. It appears that clang doesn't need any special library for coverage. With this change the following now produce identical coverage reports: ``` $ ZEPHYR_TOOLCHAIN_VARIANT=zephyr ./scripts/twister -p unit_testing \ --coverage -i -T tests/unit/intmath/ $ ZEPHYR_TOOLCHAIN_VARIANT=host ./scripts/twister -p unit_testing \ --coverage -i -T tests/unit/intmath/ $ ZEPHYR_TOOLCHAIN_VARIANT=llvm ./scripts/twister -p unit_testing \ --coverage -i --coverage-tool lcov \ --gcov-tool $(pwd)/scripts/utils/llvm-gcov.sh \ -T tests/unit/intmath/ ``` Signed-off-by: Yuval Peress <peress@google.com>
