Louis Dionne 5905e69934 [runtimes] Handle interface targets in runtimes distribution components ... As reported in [1], cxx-headers is not a valid distribution target because it is an interface target in CMake. This breaks the most basic MultiDistributionExample of the runtimes build. This patch handles interface targets by getting rid of the assumption that all distribution components have a target associated to them. It is valid for a distribution component to only have a `install-FOO` target. In the case where only `cxx-headers` is provided as a distribution component, `ninja toolchain-distribution` will not build anything after this patch, since there is effectively nothing to build for the `cxx-headers` target. However, running `ninja install-toolchain-distribution` will build everything, as expected.
