ray fails to cross build from source, because it uses mpicxx. The
problem here is that both mpi and cross building want to change the
compiler name (for injecting compiler flags and for selecting the
architecture to build for respectively). Usage of mpicxx is
fundamentally incompatible with cross building - and unnecessary. One
can simply pass the necessary flags by querying .pc files as is done for
any other library. I'm attaching a patch for your convenience.
