Hum, after thinking a bit more about this, why would we change
GNU_HOST_NAME? It sounds strange to include "buildroot" in the name of
the build machine tuple. Adding it to the target machine tuple would
seem much more appropriate, no?

I.e:

GNU_TARGET_NAME=$(ARCH)-unknown-linux-$(LIBC)$(ABI)

changed to:

GNU_TARGET_NAME=$(ARCH)-buildroot-linux-$(LIBC)$(ABI)

No?
