8# These features are optional and shall not be included in the base platform
9# Otherwise, sdk_x86-eng system images might fail to run on some

17# when compiled with clang/llvm.
18# But g++ could have internal error with march=prescott. So we will use
19# march=i686 until the g++ error is fixed or all Android modules can work around
20# that problem, see b/18174291.
