Defining this target for both host and target causes a build warning (from
ninja/make) on platforms where want_separate_host_toolset is true, since the
output filename is the same for both host and target (SHARED_INTERMEDIATE_DIR is
the same). You need to either have this output separate files for host and
target, or set it up to work with only one toolset defined somehow.
