First of all I think $(CC) containing any flags is wrong - that's what $(CFLAGS) is for. Or are you saying the compiler's built in default is to generate PIE? And then in an environment like xtf or the hypervisor (or kernels in general) such preset flags should imo simply be discarded. I.e. CFLAGS should start out all blank. So if PIE simply is the compiler default, I'd suppose there's a way to find out, and that could be leveraged for adding -no-pie. Otherwise conditional option adding will need to be used (not sure whether xtf has already inherited Xen's macros for this).
