The libdl library is already included on target builds of Android and needs to be added to the build command line with a particular order to avoid undefined references in other libraries. Fix this by only explicitly including it in host builds and relying on the implicit inclusion on target builds. Also remove the librt hack which is not longer necessary due to the AOSP build bot having been removed.
