These are inherited from the global version, the correct solution (I think) is to do `-DRUNTIMES_amdgcn-amd-amdhsa_CMAKE_CXX_FLAGS=""` or something. If that works it might be reasonable behavior to put in the cache file.

I wonder if in the general case we should force users to be more specific on which flags are intended for the runtimes or not, but that might be a little user hostile. @petrhosek WDYT?
