ANDROID: Add clang-tidy support for mixed build

Running clang-tidy/clang-analyzer with MAKE_GOALS fails in a mixed
build environment because archive files pertaining to the vmlinux are
expected as input to make rule. This would cause a failure when
generating compile_commands.json file, so we need to indicate that we
are running a mixed build environment when running clang-tidy/
clang-analyzer.
