Move the architecture guessing from Makefile.inc1 to Makefile. We
need to do this because variables specified on the command line override those specified in the Makefile. This is why we also moved from TARGET to _TARGET in Makefile, and then set TARGET on the command line when we fork a submake with Makefile.inc1. This makes mips/mips work again, even without the workaround committed to lib/libc/Makefile.
