Due to an existing bug #1771 we can't run anything we build so we have to suppress the normal multiarch build. As we can't have duplicate build rules we need to copy the bits we need from the normal multiarch Makefile so we can redefine all the run-% rules. For signals and vma-pthread they also need slightly different LDFLAGS to link to the atomic support library.

The sparc64 compiler can nominally be configured to compile 32 bit and v8plus binaries although in practice no one is now shipping them.
