# This target tests the Makefile target that builds amudprun for the host system 
# When cross-compiling, this requries access to host compilers (which differ from the usual target compilers)
# UPCR and harness have proper support for host C compilers, but unfortunately not host C++ compilers
# For non-cross-compile, we default these to GASNet's target C++ compiler
# For cross-compile, the user should set HOST_CXX(FLAGS) in the harness environment
# We deliberately ban the MANUAL_* flags here, as they may not be appropriate for the host compiler
# note this "banning" is only effective for cross-compile, otherwise MANUAL_CFLAGS is already folded into HOST_CFLAGS by harness
